Description
Technical field
The present invention relates to a kind of Ce of sandwich-like：The preparation method of YAG microcrystalline glass, the microcrystalline glass can be direct
It is packaged with light source and is matched, Simplified flowsheet, cost-effective, achievable industrial mass production.
Background technology
White light LEDs as the solid light source of new generation for progressively substituting incandescent lamp, fluorescent lamp and high-voltage gas discharging light,
Because its luminous efficiency is high, long lifespan, energy-saving and environmental protection the advantages of, it is shown that huge market potential and application prospect.Current commercial
The white light LEDs of change be mainly be the combination by blue light for InGaN chip and yellow fluorescent powder come what is realized, its operation principle is exactly
The blue light components that InGaN chips send are absorbed by yellow fluorescent powder, and the fluorescent material being excited sends gold-tinted, and unabsorbed indigo plant
Light is then combined through the gold-tinted that phosphor powder layer and fluorescent material send, so as to obtain white light.It is glimmering using silica gel or resin parcel at present
Light powder is packaged, and because phosphor material powder is close to chip pyrotoxin, chip temperature rises high-heating radiation and can reduce fluorescent material performance,

101643315B) ", " it is used for white light LEDs Ce：YAG devitrified glasses and preparation method thereof (China Patent No. CN
103183473A) ", " a kind of Ce：YAG devitrified glasses and its application (the China Patent No. CN in white light LEDs
104529166A) ", " a kind of transparent Ce：YAG devitrified glasses and its application (the China Patent No. CN in white light LEDs
104529170A) ", " the enhanced Ce of a kind of metal：YAG devitrified glasses and preparation method thereof (China Patent No. CN
103319092A)”.They are all by Ce：YAG crystallite phases are uniformly inlayed and form Ce in glass：YAG devitrified glasses.It is public
The Ce for opening：The method for packing of YAG devitrified glasses be all after the fluorescent glass dicing that will be prepared again with LED chip light source phase
Matching, this method for packing optimizes the packaging technology of market mainstream LED to a certain extent, but still there is shortcoming.Such as
The heat radiation produced after fluorescent glass and chip directly contact can reduce fluorescent material performance, and the fluorescent glass prepared is bulk
Shape, it is difficult to cutting processing, and the difficult recycling of leftover pieces cut, cause the wasting of resources, limit it industrially big
Large-scale production, prolongs and has hindered Ce：The process of YAG devitrified glass market business.
The tape casting is used as a kind of process for producing, the at present extensive use in the industries such as ceramics, plastics, glass.
The preparation technology that sandwich-like microcrystalline glass of different shapes improves devitrified glass is prepared using the tape casting, can effectively be solved
Current pure Ce：YAG devitrified glass directly contacts chip, it is difficult to cut, wastes leftover pieces and match difficulty etc. with different size light source and ask
Topic.In consideration of it, the Ce of sandwich-like：YAG microcrystalline glass is highly suitable as a kind of new fluorescent material.It is presently disclosed
Document and patent, are not involved with using the Ce of sandwich-like：YAG microcrystalline glass is glimmering as the solid-state of high-power LED encapsulation
Luminescent material.Microcrystalline glass is prepared by the tape casting simplify operation, cost-effective, achievable high-volume, large scale, Multiple Shape
