CN1305967A provides a kind of method of manufacture of rare earth yellow-green colour long-afterglow luminescent glass; This method selective oxidation strontium, aluminium sesquioxide, boron trioxide are glass matrix; Add solubility promoter and rare earth doped; After ground and mixed was even, constant temperature was treated to rare earth yellow-green colour long-afterglow luminescent glass, but only is confined to aluminate system glass.
One Chinese patent application CN1235935A provides a kind of high brightness luminous glass and method of manufacture thereof; Its fluorescent glass consists of (wt%): long afterglow luminescent powder of alkaline earth aluminate 10~30%; Glass powder 70~90%, its method of manufacture are after mixing, under 650~900 ℃ of temperature, to burn till high brightness luminous glass.It is complicated that this patent exists the host glass component, and the fluorescent material doping is high, and glass melting temperature is high, the problem of production cost height and complex process.
CN1397509A provides a kind of method of manufacture of long-afterglow luminescent glass; Its topmost characteristics are after in conventional silicate glass moulding process, mixing long after glow luminous material or glass powder with low melting point and long after glow luminous material thorough mixing, to become long-afterglow luminescent glass 700~1100 ℃ of heat-treated.The method of manufacture of this long-afterglow luminescent glass makes the commercialization of long-afterglow luminescent glass that very big development arranged, but still has certain limitation.
The present invention studies a kind of green energy conservation fluorescent material/glass composite luminescent material.This advanced luminescent material preparation technology is simple; Characteristics such as unleaded, "dead", weathering resistance, lower melting point, energy-conservation, low temperature moulding, luminous stable and steady persistence; 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.
Summary of the invention
It is high to the purpose of this invention is to provide a kind of luminous efficiency, stable performance, being easy to green energy conservation fluorescent material/glass composite luminescent material of moulding and preparation method thereof, the host glass of selecting for use is unleaded lower melting point phosphate glass.This green energy conservation fluorescent material/glass composite luminescent material has characteristics such as unleaded, "dead", weathering resistance, lower melting point, energy-conservation, low temperature moulding, luminous stable and steady persistence, under UV-light or radiation of visible light, launches long-after-glow light.
In order to carry out above-mentioned purpose; The technical scheme that the present invention adopts is: a kind of green energy conservation fluorescent material/glass composite luminescent material is characterized in that this composite luminescent material is prepared from the phosphate glass of massfraction 60~99.5% and 0.5~40% long persistence luminescent powder.The general formula of phosphate glass is (mol%): P 2O 5-ZnO-SO 3-Na 2O-SnO-M xO y
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.
