Wherein M is Mg, Ca, Sr, Ba, Ti, Te, one or more elements among Zr or the Sb.
Above-mentioned green energy conservation fluorescent material/glass composite luminescent material and preparation method thereof is characterized in that comprising following steps:
(1) phosphate matrix glass is prepared burden and batch mixing, found after mixing.200～400 ℃ of preheatings 1～5 hour, glass melting temperature was 500～900 ℃ before founding.
(2) glass grinding is become glass powder, and mix with certain mass fractional long persistence luminescent powder.With the powder compact that mixes.
(3) the powder block that suppresses is founded.Glass melting temperature is 400～800 ℃.The cooling of annealing at last promptly makes green energy conservation fluorescent material/glass composite luminescent material.
The glass transformation temperature Tg of resulting green energy conservation fluorescent material/glass composite luminescent material is 200～400 ℃.
The invention has the beneficial effects as follows: because the phosphate matrix glass of being selected for use has low glass transformation temperature Tg, and the not leaded heavy metal that waits, pollution-free so it is simple to have preparation technology, low temperature moulding, characteristics such as green energy conservation.Long persistence luminescent powder is mixed in the phosphate matrix glass powder; Through it is founded processing; Long-afterglow fluorescent pruinescence host glass is coated, thereby obtain the designability of high transparent, chemicalstability, thermostability, weathering resistance, uniqueness, the composite luminescent material of good performances such as workability with good long-persistence luminous performance of long persistence luminescent powder and phosphate matrix glass.Green energy conservation fluorescent material of the present invention/glass composite luminescent material can be launched long-after-glow light under the exciting of visible light or UV-light.Adopt this green energy conservation fluorescent material/glass composite luminescent material preparation method to promoting the new energy development and the energy-conservation cause of China, reduce and pollute, realize that the strategy of sustainable development of national economy has great importance.
