Problems solved by technology

The luminescence of rare earth ions comes from the transition of 4f-4f electron shells. Because of the shielding of the outermost electrons, the color and wavelength width of the luminescence are greatly limited, which cannot meet the requirements of various luminescence required for the display of the mechanoluminescence sensor.

Abstract

The invention discloses a microcrystalline glass with mechanoluminescence. The microcrystalline glass contains the following components in percentage by mole: 1-20% of Na2CO3, 40-60% of SiO2, 10-30% of trivalent oxide, 0.005-10% of MnCO3 and 10-30% of ZnO. The trivalent oxide is more than one of Al2O3 and Ga2O3. The invention also discloses a preparation method of the microcrystalline glass with mechanoluminescence. The mechanoluminescence wavelength of the microcrystalline glass under the action of applied force is located at 475-575nm, and the emission peak is located at 506nm; and the microcrystalline glass has mechanoluminescence.

Description

technical field [0001] The invention relates to glass-ceramics, in particular to glass-ceramics with mechanoluminescent properties and a preparation method thereof. Background technique [0002] With the development of sensor display technology, electroluminescent materials have attracted more and more attention and research because of their great potential application value. Mechanoluminescent materials are expected to be used in many fields such as electronic displays, vacuum fluorescent displays, thin-film light-emitting displays, and biomedical disease monitoring. At present, the materials capable of realizing mechanoluminescence are mainly crystals doped with rare earth ions and transition metal ions. However, preparing phosphor materials with mechanoluminescent properties and then mixing and melting them with glass materials, the preparation process is cumbersome and the preparation cost is increased. Glass-ceramic is a kind of hybrid material with nanocrystals distr...
