Abstract
The present invention has synthesized rare earth serial phosphor (Re) O
2O
2S:X (Re=Y wherein, Gd, La; X=Eu, Tb, one or more elements of Tm), also determined rare-earth phosphor (Re)
2O
2The luminous correlationship with temperature of S:X; And determined that fluor when ultraviolet excitation, sends the light of different colours under different temperature, and also adopt caking agent to bond to the monitoring site of thermal objects, realized measurement to temperature.
Description
A kind of rare earth luminous fluor of in the optical measurement technology field, using.
Usually measuring temperature is directly to use glass-stem thermometer, and thermoelectricity is occasionally used semiconducter device, etc.But at high-voltage, upfield or to metallic substance the extensive chemical corrosion is arranged, flowable state or at a distance in object and the big area scope under the situation such as uneven temperature is used said temperature meter or electronic technology thermometric, obviously is inconvenient.Therefore, adopt optical measurement technology, just more convenient, and the key that realizes this technology is to seek a kind of width of cloth to penetrate fluorescent material with temperature correlation, because the relative spectral intensity of this material or luminous total intensity change with the change of temperature, by the photoconductive fiber conduction, use instrument and detect the photoelectricity variation and be converted into the temperature demonstration.About fluor itself, chemical formula be:
(Re)
2O
2S
3The rare earth serial phosphor of X is the ordinary method preparation of adopting synthetic sulphur rare earth oxide fluor, by (Y, Eu, Tb, Tm)
2O
3: S: Na
2CO
3: KH
2PO
2=100: 30: 30: 5 weight ratio weighing, grind mixing, the alumina crucible of packing into is added a cover, and in 1150～1250 ℃ of calcinings 1-2 hour, the cooling of coming out of the stove was selected materials under UV-light, and the salt acid soak with 2-4N washes with water to neutrality again, suction filtration, oven dry promptly obtains Y
2O
2S: Eu(yttrium oxysulfide: europium), La
2O
2EuTb(sulphur lanthanum trioxide: europium, terbium) and La S:
2O
2S: EuTb, Tm(sulphur lanthanum trioxide: europium, terbium thulium).For these fluor, not being reported is used for measuring technology.
For making these fluor be used for thermometry, the present invention has determined the correlation properties curve of the luminous and Wen Guang of this class fluor.(seeing accompanying drawing 1 and accompanying drawing 2) may be obvious that from figure: under 30～300 ℃ of temperature, the luminous feature of 450～650nm is different, and temperature high luminous intensity more diminishes more.In addition, the present invention has also determined this class fluor glow color and temperature relation under ultraviolet ray or cathode-ray exciting, and is as shown in the table:
Can find out that from table the glow color of this class rare-earth phosphor and the correlationship of temperature are clearly, promptly under normal temperature and comparatively high temps, along with the temperature difference, luminous color is also different, according to this character, this class fluor is to be used for the temperature survey of comparatively high temps object.
In order to solve the temperature survey of high voltage electric power equip ment, make the watch-dog works better, try to avert accidents, fluor is bonded to the monitoring site of thermal objects with the water glass caking agent of 2-5%, use the 253.7nm uviolizing, the heating situation during in order to the work of supervision high voltage installation.
Measure the temperature of higher temperatures object with the present invention, method is easy, does not need valuable instrument and equipment, and is good in economic efficiency.
Description of drawings: accompanying drawing 1 and accompanying drawing 2 are luminous and correlation properties curve temperature.Abscissa is a number of wavelengths.In Fig. 1 curve for from the top down corresponding to temperature 30,100,160,200,250,300 ℃ of following gained curves; Be gained curve under 22,60,100,150,200,300,400 ℃ of temperature from the top down in Fig. 2.
