Abstract
The invention discloses glass ceramics for exciting white-light LED (Light Emitting Diode) lamps. The glass ceramics are prepared through grinding the following ingredients in parts: 60-70 parts of silicon carbide, 80-100 parts of aluminum nitride, 40-55 parts of mullite powder, 35-40 parts of ceramsite powder, 8-10 parts of magnesia, 6-8 parts of aluminum hydroxide, 5-8 parts of calcium carbonate, 10-12 parts of sodium oxide, 8-12 parts of aluminum fluoride, 12-15 parts of erbium oxide, 6-8 parts of indium oxide, 9-12 parts of silicon monoxide, 6-8 parts of titanium sesquioxide, 8-10 parts of zinc oxide and 10-15 parts of manganese sulfate; and then carrying out firing. The glass ceramics for exciting the white-light LED lamps are simple in preparation process and low in cost, are non-toxic and pollution-free, have good mechanical properties and thermal stability and are hopefully developed and applied to the manufacturing of ultraviolet chip excited novel white-light LED devices.
Description
Technical field
The present invention relates to a kind of solid luminescence ceramic material, particularly relate to one and realize the excited white light LED glass ceramics of tunable multicolor luminous (including white light).
Background technology
White light LEDs has high-effect, total solids, advantage pollution-free, long-life, replaces traditional electric filament lamp and fluorescent lamp gradually, becomes the lighting source that a class is novel.The manufacture method of white light LEDs usually excites YAG:Ce3+ fluorescent material with efficient GaN base blue led, and the gold-tinted that YAG sends forms white light with residue blue light.But, the white light LED part prepared in this way of profit lacks red-light spectrum, and luminescence, and display index is not high.In order to solve this problem, there has been proposed another kind of scheme, namely adopt black light chip to excite three primary colours (red, green, blue) fluorescent material to form white light LED part.This type of white light LEDs has that color reducibility is good, color rendering index is high, the advantage that light efficiency is high.But due to the epoxy resin as encapsulating material under ultraviolet light long-term irradiation easily aging, its service life is not long.Therefore, find a kind of novel solid luminescent material launching intense white light and ultraviolet resistance irradiation (properity is stable) under near ultraviolet excitation and seem very necessary.In recent years, people have studied the white light emission glass ceramics that Eu2+/Mn2+, Ce3+/Dy3+, Eu2+/Sm3+, Eu2+/Eu3+/Tb3+ are co-doped with in succession.Glass ceramic material can be processed into tabular and directly overlay on chip, and has good heat, chemical stability, is the desirable host material preparing white light LED part.
But it is not high that the LED glass ceramics of prior art still also exists stability, the shortcomings such as radiating efficiency is undesirable.
Summary of the invention
The present invention is intended to overcome the defect of prior art, purpose is in that to provide a kind of excited white light LED glass ceramics, LED glass ceramics preparation technology is simple, with low cost for this excited white light, nontoxic pollution-free, there is good mechanical property and thermal stability, it is expected to exploitation is applied to build the novel white-light LED component that ultraviolet chip excites.
The technical solution adopted for the present invention to solve the technical problems is: a kind of excited white light LED glass ceramics, formed by polished the firing of the component of following number: 60-70 part carborundum, 80-100 part aluminium nitride, 40-55 part mullite powder, 35-40 part haydite powder, 8-10 part magnesium oxide, 6-8 part aluminium hydroxide, 5-8 part calcium carbonate, 10-12 part sodium oxide, 8-12 part aluminium fluoride, 12-15 part Erbia, 6-8 part Indium sesquioxide., 9-12 part silicon monoxide, 6-8 part titanium sesquioxide, 8-10 part zinc oxide, 10-15 part manganese sulfate.
Further, polished the firing of the component of following number form: 60 parts of carborundums, 80 parts of aluminium nitride, 40 parts of mullite powders, 35 parts of haydite powder, 8 parts of magnesium oxide, 6 parts of aluminium hydroxide, 5 parts of calcium carbonate, 10 parts of sodium oxide, 8 parts of aluminium fluoride, 12 parts of Erbias, 6 parts of Indium sesquioxide .s, 9 parts of silicon monoxides, 6 parts of titanium sesquioxides, 8 parts of zinc oxide, 10 parts of manganese sulfates.
Or, polished the firing of the component of following number form: 70 parts of carborundums, 100 parts of aluminium nitride, 55 parts of mullite powders, 40 parts of haydite powder, 10 parts of magnesium oxide, 8 parts of aluminium hydroxide, 8 parts of calcium carbonate, 12 parts of sodium oxide, 12 parts of aluminium fluoride, 15 parts of Erbias, 8 parts of Indium sesquioxide .s, 12 parts of silicon monoxides, 8 parts of titanium sesquioxides, 10 parts of zinc oxide, 15 parts of manganese sulfates.
In sum, the excited white light LED glass ceramics preparation technology of the present invention is simple, with low cost, and nontoxic pollution-free has good mechanical property and thermal stability, it is expected to exploitation is applied to build the novel white-light LED component that ultraviolet chip excites.
