Abstract

The invention discloses a high brightness mechanical luminescent material and a preparation method thereof, and relates to a mechanical luminescent material capable of emitting bright yellow and orange light under the action of mechanical force such as friction force, pressure and impact force, and a preparation method thereof. The invention solves the problem that the conventional aluminate system mechanical luminescent material has a single system and a single color of emitted light. The material has the general formula of M2-x-y-z-wZnwP2O7:Eux,Mny,Lnz, wherein M refers to one or a combination of Ca and Sr, an arbitrary combination of Ca, Sr and Mg, or an arbitrary combination of Ca, Sr and Ba; Ln refers to one or an arbitrary combination of La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu; and x is more than or equal to 0.0001 and less than or equal to 0.20, y is more than or equal to 0.001 and less than or equal to 0.30, z is more than 0 and less than or equal to 0.20, and w is more than 0 and less than or equal to 0.20. The preparation process for the luminescent material is simple, low in cost and pollution-free.

Description

technical field [0001] The invention relates to a high-brightness mechanical luminescent material and a preparation method thereof, in particular to a mechanical luminescent material capable of emitting bright yellow-orange light under mechanical forces such as friction, pressure or impact, and a preparation method thereof. Background technique [0002] Mechanoluminescent materials are a general term for a class of materials that can convert mechanical energy into light energy. Such materials can be used in triboluminescent anti-counterfeiting inks, pressure-sensitive luminous bodies, pressure detection sensors, ultra-precision processing image monitoring systems, stress flaw detection and earthquake early warning and other fields. At present, mechanoluminescent materials mainly include inorganic and organic materials. Although there are many types of organic complex materials, their luminous brightness, stability and practicability are poor. Phosphoric luminescent material...
