Photoluminescent ceramic powder, preparation method thereof, ceramic glaze, ink and application
The invention discloses photoluminescent ceramic powder and a preparation method thereof, ceramic glaze, ink and application, the chemical general formula of the photoluminescent ceramic powder is LaMgAl5PO19: xCe, yTb, x is equal to 0.01-0.5, and y is equal to 0.01-1. The photoluminescent ceramic powder provided by the invention is white powder, can bear the high temperature of 1300 DEG C, can emit green light after being irradiated and excited by ultraviolet light, and returns to the original white powder state after ultraviolet exciting light is removed. The photoluminescence ceramic powder has the advantages that the photoluminescence property is good, the color change response time is short, the thermal stability is good, the fatigue resistance is good, the photoluminescence effect is still good after high-temperature sintering, the photoluminescence ceramic powder is compatible with a ceramic tile high-temperature sintering process, the influence on patterns of ceramic tiles is small, and the like. The ceramic glaze can be further prepared into ceramic glaze or ceramic ink, then patterns and codes can be formed on the surface of a ceramic tile through ceramic silk-screen printing, rubber roller printing or ink-jet printing, authenticity is identified and distinguished through an ultraviolet light detector, and the ceramic glaze has wide application prospects in the field of ceramic tile anti-counterfeiting.
本发明公开一种光致发光陶瓷粉体及其制备方法、陶瓷釉料及墨水与应用，所述光致发光陶瓷粉体的化学通式为LaMgAl5PO19:xCe,yTb，其中x＝0.01～0.5，y＝0.01～1。本发明提供的光致发光陶瓷粉体为白色粉体，可以经受1300℃高温，经紫外光辐照激发后能发绿色光，紫外激发光撤除后又回到原始白色粉体状态。所述光致发光陶瓷粉体自身具有光致发光性质好，变色响应时间快，热稳定性好，抗疲劳性能好，在高温烧成后仍具有良好的光致发光效果，与陶瓷砖高温烧结工艺相兼容，对陶瓷砖本身图案影响小等优点，其可进一步制成陶瓷釉料或陶瓷墨水，进而可以通过陶瓷丝网印刷、胶辊印刷或喷墨打印在陶瓷砖表面形成图案及编码，经紫外光检测器识别，辨别真伪，在陶瓷砖防伪领域具有广泛的应用前景。
