Long persistence luminescent glass and manufacturing method thereof

Abstract

A new kind of long-afterglow phosphorescent glass is composed of 5~60 wt% long-afterglow material which particle size is 10~100 um and 40~95wt% matrix glass the softening tempereture of which is 400 DEG C ~1100 DEG C.The long-afterglow phosphorescent glass can long-afterglow phosphoresce for 4 to 12 hours in the dark after stimulating by visible light or uv,the luminescence color is yellow, yellowish green,green,blue green,orange red,red etc.The line expansion coefficient of matrix glass is (15~110)*10[-7] / DEG C and the emitting spectrum is 440~650 nm.The manufacturing method of this new long-afterglow phosphorescent glass is that making the long-afterglow material and matrix glass into phosphorescent glass powder or phosphorescent glass block firstly and then producting long-afterglow phosphorescent glass according to the conventional production technology that incorporation into silicate glass,aluminate glass,lead glass and quartz glass.

Description

technical field [0001] The invention relates to material glass, in particular to a novel long afterglow luminous glass with self-luminous function and a manufacturing method thereof. Background technique [0002] In the 1990s, two types of long-lasting luminescent materials, aluminate system and silicate system, were successively invented. These two types of long-lasting luminescent materials have greatly surpassed the traditional sulfide series luminescent materials in terms of luminous brightness, afterglow time, and chemical stability. However, traditional sulfide luminescent materials have an irreplaceable role in some fields. also play an important role. [0003] Glass plays a very important role in people's daily life, and the combination of glass and luminescent materials is a new field. As a new type of material, long afterglow luminous glass has a wide range of applications in construction, energy saving, aviation, emergency lighting,...

AI Technical Summary

Problems solved by technology

[0007] 1) The production method is single and the application range is narrow;

[0008] 2) The luminescent powder is made of alkaline earth aluminate luminescent material, and the material is single

[0012] CN1405106A provides a kind of photochromic luminescent glass and its production method, its main feature is that it contains 85-92% of glass frit and 8-15% of luminous substance, and its various luminescent colors are determined by the composition and proportion of luminescent substance , but due to the low content of luminescent materials, it will inevitably affect the afterglow brightness of luminescent glass, and the limitations of the method lead to great limitations in the types, artistic forms, and production processes of luminescent glass.

[0013] In the prior art, the luminescent material and the matrix glass cannot achieve the purpose of organic combination in the technical conditions such as composition ratio and sintering temperature, resulting in a single variety of luminescent glass, which cannot reflect the beauty of the glass; the luminescence caused by the high sintering temperature of the glass The brightness is low; the content of luminescent powder is limited, which affects the luminous brightness; the limitation of the process affects the use range of the matrix glass; there are few production methods, and it is impossible to realize a series of defects such as a variety of luminescent glass products.
