Description

Aluminum oxide/lanthanide perovskite ceramic composite light absorber and preparation method thereof
Technical Field
The invention relates to an alumina/lanthanide perovskite ceramic composite light absorber and a preparation method thereof, wherein the film-based structure has the characteristics of laser damage resistance, high-temperature thermal shock resistance and wide-spectrum high absorption, and can be applied to components in the field of photothermal conversion such as laser energy meters, laser power meters, thermal radiation detectors and the like.
Background
For the measurement of high-power laser, a thermopile type laser power meter/energy meter is mainly used, the test principle is that a light absorber in a probe absorbs light energy of incident laser to convert the light energy into heat energy, temperature gradient fields are formed at the center and two ends of the edge of the light absorber, thermoelectric materials in the probe generate thermoelectric electromotive force, and the magnitude of the electromotive force depends on the magnitude of the heat energy converted by the laser. Therefore, the light absorption performance, the laser damage resistance and the thermal shock resistance of the light absorber in the probe directly determine the response strength of a laser power meter/energy meter test and the power of the test laser wavelength, and are core components of the thermopile type laser power meter/energy meter detector.
At present, the light absorption materials (including thin films and blocks) of the thermopile type laser power meter/energy meter probe mainly include metal nano materials (such as gold black, silver black, iron black, and the like), carbon materials, sulfides, carbides, nitrides, optical glass, and the like. However, these materials have a narrow absorption wavelength range (mostly in the range of 0.2 to 2.5 μm) and oxygen-rich rings at high temperaturesEasily lose efficacy in the environment (more than or equal to 1000 ℃). Most of the light absorbing materials in high temperature oxygen-rich environment are metal oxides and composite oxide materials thereof, for example, the documents "Lu Y, et al high thermal radiation of Ca-doped lanthanum chloride, RSC Advances,2015, 30667" are prepared by solid phase reaction method, la-doped lanthanide chromate ceramic, la 30667 0.5 Ca 0.5 CrO 3 The light absorption performance of the solar cell is optimal, and the solar energy absorptivity reaches 95%. In the document He Zhiyong and the like, (Ca, fe) codoped lanthanum ceram has the near infrared absorption performance, reported in silicate science, 2016, 44. These documents are significantly different in both material and structure compared to the present application, e.g., lanthanum manganate is not used as the main material of the light absorber matrix, and the structure does not exhibit the characteristic of pore gradient, much less film-based structure.
Although some also employ LaMnO 3 As light-absorbing materials, there are described in the literature "Zhang PX, et al 3 thin film laser energy/power meter,Optics&Laser Technology,2004,36 1-x Ca x MnO 3 (x is more than or equal to 0.05 and less than or equal to 0.33) is deposited on LaAlO 3 Preparing La on the substrate 1-x Ca x MnO 3 The film acts as a light absorbing layer for the laser power meter and energy meter. Compared with the present application, la thereof 1-x Ca x MnO 3 Compared with the pore gradient lanthanide perovskite ceramic, the pore gradient lanthanide perovskite ceramic is a compact thin film, the existing form and the preparation method are obviously different, and no transition layer exists at the interface of a film-based structure. The document "Afifah N, et al, enhancement of phosphor to ultraviolet region by coupling Perovskite LaMnO 3 with TiO 2 nanoparticles, international Symposium on Current Progress in Functional Materials,2017,188 3 /TiO 2 LaMnO of mole ratio 3 /TiO 2 Nanocomposite material of effectively improvedThe material has absorptivity in ultraviolet region. Compared with the application, the LaMnO thereof 3 The ceramic is nano powder and a composite material, and compared with the pore gradient lanthanide perovskite ceramic, the ceramic has different material compositions, structures and preparation methods and does not have a film-based structure.
The damage of the laser to the optical thin film element is a main cause affecting the service life of the high-power laser optical thin film element, so that it is important to improve the laser damage resistance of the optical thin film. Generally speaking, the laser damage resistant material is mainly ceramic, especially oxide ceramic material, such as document "Li Zhaoyan, etc., the laser damage resistant capability research of the surface of engineering ceramic, the photonics report, 2017, 46. "research on zirconia (ZrO) 2 ) Alumina (Al) 2 O 3 ) Silicon nitride ceramics (Si) 3 N 4 ) Steatite porcelain (MgO/SiO) 2 ) The laser damage resistance of the 304 stainless steel (Fe/C/Cr) and 5052 aluminum alloy (Al/Mg/Cu) materials under nanosecond laser irradiation shows that the laser damage resistance threshold of the alumina ceramic is the highest. Therefore, an alumina material is selected as a thin film with a film-based structure resistant to laser damage. At present, al 2 O 3 The film preparation technology comprises physical vapor deposition, thermal evaporation deposition, magnetron sputtering, ion beam assisted deposition, pulse laser deposition, plasma arc plating, chemical vapor deposition, sol-gel, anodic oxidation and the like, for example, in the document' Liu Zhi super and the like, research on 1064nm laser damage characteristics of an ALD alumina single-layer film, optics is applied, 2011, 32 2 O 3 A film. Compared with the application, compact Al is not plated on the pore gradient lanthanide series perovskite ceramic substrate 2 O 3 The ceramic film has no transition layer at the film-substrate interface.
In summary, the above documents are compared with the present application, and besides the forms, materials and specific preparation methods existing in the light absorber for laser power meter/energy meter are different from those of the film-based structure of the present invention, the light absorber in the above documents does not exhibit a uniform gradient porous structure, nor is Al plating applied to the surface of the light absorber 2 O 3 And (3) a membrane. The application is due toIs designed and prepared to contain Al 2 O 3 The film, the pore gradient lanthanide perovskite ceramic body and the film-based structured light absorber of the intermediate transition layer have the comprehensive advantages of laser damage resistance, wide spectrum high absorption and high temperature thermal shock resistance.

The preparation method of the light absorber comprises the following steps:
(1) Synthesizing lanthanide perovskite ceramic powder with wide spectrum and high absorption by a solid phase method: lanthanum oxide, manganese oxide, calcium carbonate, lithium carbonate and chromium oxide are respectively added according to LaMnO 3 、La 1-x Ca x MnO 3 、La 1-y Li y MnO 3 And La 1-z Ca z CrO 3 The stoichiometric ratio (x is more than or equal to 0.3 and less than or equal to 0.7,0.3 and less than or equal to y is more than or equal to 0.7,0.3 and less than or equal to z is less than or equal to 0.7) is mixed and then solid phase sintering is carried out (sintering temperatureThe temperature is 1000-1200 ℃, the heating rate is 5 ℃/min, the heat preservation time is 2-5 h), ball milling is carried out for 24-48 h at the speed of 300 r/min and the ball material weight ratio of 3:1, and lanthanum manganate, calcium-doped lanthanum manganate, lithium-doped lanthanum manganate and calcium-doped lanthanum chromate powder are respectively obtained after ball milling and sieving; the lanthanide perovskite ceramic used for the light absorber is prepared in the solid-phase synthesis process.
(2) Preparing a pore gradient seven-layer structure lanthanide perovskite ceramic substrate: uniformly mixing the four kinds of powder with a polyvinyl alcohol solution, and sieving the mixture through a 200-mesh sieve to obtain granulated powder; wherein the weight ratio of polyvinyl alcohol to polyvinyl alcohol solution in the polyvinyl alcohol solution is 5-10%, and the weight ratio of polyvinyl alcohol solution to ceramic powder is 8-10%; then evenly spreading the granulated powder on the surface of the substrate

In the hot press mold of (1), the first and seventh layers are LaMnO 3 The second and sixth layers are La 1-x Ca x MnO 3 The third and fifth layers are La 1-y Li y MnO 3 The fourth layer is La 1-z Ca z CrO 3 Wherein the weight of the powder of each layer is between 0.2 and 0.8g, and the green body is obtained by keeping the pressure for 5 to 10min under the mould pressing of 10 to 15 Mpa; sintering at 1400-1500 ℃ and 10-20 kPa for 2-4 h under the argon environment to obtain a pore gradient lanthanide perovskite ceramic substrate with a compact surface layer and a porous middle layer, wherein the thickness of each layer is 0.05-0.2mm, and the total thickness is 0.5-1mm;
