Abstract

The invention discloses a transparent ceramic material with mechanoluminescence property and a preparation method of the transparent ceramic material, aims to provide a pressure sensing material withthe mechanoluminescence property and belongs to the technical field of the transparent ceramic material. The general formula of chemical composition of the transparent ceramic material is Se(10-y-z)Al(6-x)BxO19:yEu<2+>,zRe<3+>, wherein Re is one or combination of more than one of Dy, Gd and Nd, value ranges of x, y and z are as follows: x is larger than or equal to 0.1 and smaller than or equal to0.5, y is larger than or equal to 0.01 and smaller than or equal to 0.05, and z is larger than or equal to 0.01 and smaller than or equal to 0.05. The luminescence center of the transparent ceramic material is Eu<2+> ions, and the mechanoluminescence effect of the transparent ceramic material can be effectively enhanced by introducing rare earth impurity ions such as Dy<3+>, Gd<3+> and Nd<3+>. The transparent ceramic material has the characteristics of high compressive strength, remarkable mechanoluminescence effect and the like and can be applied to pressure sensing components in pressure sensors.
