Abstract

The invention belongs to the technical field of mechanoluminescent ceramic materials, and particularly relates to mechanoluminescent ceramic material powder particle ink as well as a preparation method and application thereof. The blue mechanoluminescence ceramic material powder particle printing ink is characterized in that the blue mechanoluminescence ceramic material powder particle printing ink is prepared from blue mechanoluminescent ceramic material powder particle suspension in a solvent. The general formula of the chemical composition of the ceramic material is Ca (1-x-y) Al3O4N: xEu <2 + >, yRe < 3 + >, Re is one or a combination of two of Nd and Sm, x is greater than or equal to 0.01 and less than or equal to 0.1, and y is greater than or equal to 0.01 and less than or equal to0.2. By coating a substrate with the ink, a blue mechanoluminescence sensor is prepared. The pressure sensor prepared by the method is applied to a wind tunnel experiment.

Description

[0001] The present invention is a divisional application. The application number of the original application is: 201711061636.7, the application date is: 2017-11-02, and the patent name is: a blue mechanoluminescent ceramic material and its preparation method. technical field [0002] The invention belongs to the technical field of mechanoluminescent materials, and in particular relates to a mechanoluminescent ceramic material powder particle ink and a preparation method and application thereof. Background technique [0003] The physical phenomenon that materials emit visible light under the action of stress, friction, fracture or ultrasonic vibration is called mechanoluminescence. Like long-lasting luminescence, mechanoluminescence is also a physical phenomenon that has been recognized by human beings for a long time. There are many materials that can produce mechanoluminescence, including organic and inorganic materials, such as sugar crystals, quartz crystals, and the lon...
