Abstract

The invention discloses blue-green energy accumulation type glow stones and a preparation method thereof. The blue-green energy accumulation type glow stones are prepared by taking blue-green long afterglow luminescent powder xMnO.(1-0.5x)ZrO2.SiO2 (x is 0.003 to 0.15), boric acid and zirconium hydrogen phosphate as raw materials, mixing the raw materials and pressing and molding, and then calcining at high temperature. The preparation method of the glow stones is simple and the cost is low; after the obtained blue-green glow stones are irradiated for 15 minutes, blue-green light can be observed in the dark and the luminescent time reaches 10 to 13 hours; the blue-green energy accumulation type glow stones have high rigidity and are tested through a jade hardness tester to find out that the Moh's hardness of the glow stones is 6.2 to 7.0 Mohs; after the glow stones are polished and ground, the surfaces are translucent, so that the glow stones have very good ornamental value.

Description

technical field [0001] The invention belongs to the technical field of inorganic material preparation, and in particular relates to a novel blue-green energy storage type luminescent stone and a preparation method thereof. Background technique [0002] Luminous stone, also known as night pearl, can continue to glow in the dark after being excited by light. Because natural luminous pearls are very rare and expensive, it is difficult for ordinary people to own them. In addition, natural luminous pearls generally contain radioactive elements, which affect human health. Therefore, artificially synthesized luminous pearls that are non-toxic, harmless, have a long luminescence time, and have ornamental and collection values ​​have good commercial application prospects. [0003] Long afterglow luminescent material is a kind of luminescent powder with "night pearl" phenomenon. By processing the long afterglow powder into a block-shaped stone with high hardness, and then cutting, ...
