Title:
LANTHANIDE LUMINESCENT MATERIAL HAVING TRIPLE LUMINESCENT CHANNEL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/034132
Kind Code:
A1
Abstract:
The present invention relates to a lanthanide luminescent material having triple luminescent channels and a preparation method therefor. The preparation method comprises the following steps: according to a molar ratio of 0.5-1 : 4-8, reacting a nitrate of a lanthanide metal and phenanthroline under closed conditions, wherein the reaction temperature is 130ºC-150ºC, and the reaction time is 2-3 days; and cooling same to obtain a crystal. The crystal is the lanthanide luminescent material having triple luminescent channels. The preparation method for the lanthanide luminescent material of the present invention is simple, efficient and green and environmentally friendly, and the luminescent material prepared thereby has intrinsic, excellent and efficient triple luminescent effects, i.e. photoluminescence, X-ray luminescence and mechanoluminescence.
