- Hg Ca it may be substituted with Sr or the like.
- Calco one Gen i.e. oxygen group elements Ru is used.
- This chalcogen contains oxygen, sulfur, selenium, tellurium, and podium, but polonium is less preferred because of its high metallic nature.
- This Calco one Gen also usually used alone with each of AA 2, other non-metal in the range properties not there a Nere of also may also semiconductor with two or more thereof, if desired ⁇ Mechanoluminescence material of the present invention may be substituted with an element such as silicon, nitrogen, boron, arsenic, etc. It is preferable that the main component be a substance, selenide, or telluride.

Furthermore, if a material composed of undistorted or microcrystallites is used, a material exhibiting strong stress emission such as laser light can be obtained.
- the raw material forming the semiconductor represented by the general formula (II) and the semiconductor raw material represented by the general formula (in) are mixed at a specific ratio, for example, x is 0.01 to 99.99, preferably 0!
- the mixture is mixed in a ratio of up to 99.9, and the mixture is filled in a quartz tube, heated under vacuum, and the raw material is sublimated on the high temperature side using a temperature gradient and recrystallized on the low temperature side.

- the quartz tube is evacuated to a vacuum, after replacing the inside with argon or hydrogen, 1 0 4 Pa or less, rather preferably are shorted with to the high vacuum below 1 0- 2 Pa, the emission intensity Can be improved.
- the stress emission intensity depends on both the crystal particle diameter and the lattice strain. That is, as the crystal particle diameter increases, the luminescence intensity decreases, and when the crystal particle size decreases, for example, nano-sized crystal particles exhibit high luminescence intensity.
- the crystal grain size is preferably 35 nm or less, particularly preferably 20 nm or less. The crystal grain size can be measured by X-ray diffraction.
- microcrystals when particle distortion is present, the luminescence intensity is significantly reduced. Therefore, in order to obtain a high luminescence intensity, it is preferable to form microcrystals with less distortion.
- the crystal grain size and crystal distortion can be analyzed simultaneously by X-ray diffraction. In other words, the half-width in the Gaussian distribution and the Lorentz distribution can be obtained independently by profile fitting the Pseudo-voigt relational expression for a wide range of diffraction lines.
- the crystal grain size and lattice strain can be obtained at the same time (see Kodansha, June 1, 1999, published by Kodansha, written by Takamitsu Yamanaka, "Material Analysis by Powder X-ray Diffraction", page 95).
- the luminous intensity of the mechanoluminescence material of the present invention changes depending on the magnitude of mechanical energy serving as an excitation source, that is, the mechanical force.
- the emission intensity of a mechanoluminescence material increases as the applied mechanical action force increases, but the mechanical action force for emitting light has a minimum energy, that is, a threshold value.
- This threshold value depends on the composition of the material, and varies from a material that emits light with a small energy of less than 1 N to a device that emits light only when a large amount of energy that causes destruction of the material is applied.
- the mechanoluminescence material of the present invention can emit light only by applying an extremely small external force.
- the mechanoluminescence material of the present invention may be in the form of a powder, but may be formed into a block or a coating, or may be processed into a laminate or a composite with a plastic.
- the particle size can be arbitrarily obtained from the nano size to the mm size by controlling the firing conditions at the time of manufacturing the material. Then, the ultrafine particles having a particle size smaller than the diameter of the sub-micron thus obtained emit strong light such as laser light by mechanical stimulation, and this light emission is repeatedly applied. It is stable without being damped by the applied mechanical external force.
- Example 1
- the particle size of the fine crystals obtained in this way was determined by X-ray diffraction and is shown in Table 1.
- FIG. 4 is a graph showing the change with time of the light emission generated at this time. As can be seen from this figure, this emission does not attenuate due to repeated loading.
- Figure 5 shows the results as a graph. From this figure, it can be seen that the luminescence intensity increases as the applied load increases. Using this graph, the magnitude of the applied mechanical acting force can be determined by measuring the luminescence intensity. Examples 2 to 10
- Table 1 shows the particle diameters of the crystal grains and the relative luminescence intensity of SrAl 2 O 4 : Eu assuming that the luminescence intensity was 100 for these materials.
- M 1 is Zn or Zn partially substituted
- M 2 is Mn
- a 1 and A 2 are the same element, for example, S or Te. It shows high emission intensity. Also, when the crystal particle diameter is less than 20 nm, there is a tendency to show a strong emission intensity.
- a novel mechanoluminescence material which emits light strongly by a mechanical external force such as frictional force, shear force, impact force, pressure, tension, and torsion. It can be used for sensors, displays, amusement devices, observation of stress distribution, etc.
