Abstract
The invention discloses white light-emitting glass. Ce<3+>\Eu<2+>, Tb<3+> and Mn<2+>\Eu<3+> ions are used as a trichromatic luminescent center to be doped into a multicomponent borosilicate glass matrix to prepare borosilicate light-emitting glass doped with Eu and Tb, Ce, Tb and Mn or Ce, Tb and Eu. The invention also provides a method for preparing the borosilicate light-emitting glass. The borosilicate light-emitting glass can be excited effectively by long-wave ultraviolet light to emit red, green and blue trichromatic light, so that white light is compounded, and the problem of chromatic aberration caused by different luminescent service lives of fluorescent powder and blue-light chips; and simultaneously, the conventional complex process for coating the fluorescent powder is avoided, and the method is expected to be used for manufacturing a novel white light-emitting diode (LED) device based on the excitation of ultraviolet chips.
Description
Technical field
The present invention relates to the solid luminescent material field, especially relate to a kind of glass and preparation method thereof that emits white light that can be under long wave ultraviolet light excites.
Background technology
As after incandescent light, luminescent lamp and HID (high-intensity discharge) lamp the 4th generation lighting source white light LEDs, environmental protection energy-conservation, plurality of advantages such as the life-span is long, volume is little with it, in illumination and demonstration field great application prospect is arranged.At present, common commercial white light LEDs is by blue light InGaN chip and doped Ce
3+The yellow fluorescent powder of yttrium aluminum garnet (YAG) be packaged together and process, fluorescent material adopts and to be coated on the led chip and to be mixed in the epoxy resin.Its principle of luminosity is: by InGaN chip part blue light that sends and the YAG:Ce that is excited
3+Yellow light mix that yellow fluorescent powder sends output white light, this LED have advantages such as the preparation of being prone to, cost are low, high brightness.Yet, because fluorescent material is different with the luminescent lifetime of InGaN chip, can aberration appear after use for some time and color developing is low.In order to overcome the above problems, can realize the preparation of white light LEDs through the mode that adopts the ultraviolet leds chip to add three primary colors fluorescent powder.Like this, what chip sent can not be absorbed by fluorescent material by the UV-light of finding of naked eye fully, makes to mix the output white light behind its stimulated emission red, green, blue three coloured light, has improved color developing when avoiding aberration.
Fluorescent glass is one type of important fluorescent material, and the most successful and topmost application at present is embodied in superpower laser (the extensive Nd that uses in the laser-ignition unit
3The phosphate glass of ion doping), opticfiber communication (Er
3+Ion, Tm
3+The silica glass of ion doping) and optical fiber laser (Yb
3+The glass of ion doping) field.The fluorescent powder material of comparing, fluorescent glass has lot of advantages, and is simple such as preparation technology, cost is low, favorable repeatability; The good transparency is easy to realize common emission of RGB or the like.These advantages make the substitute of fluorescent glass as fluorescent material, become the another kind of effective way that realizes white light LEDs.
Summary of the invention
The technical issues that need to address of the present invention be disclose a kind of can be at long wave ultraviolet light (glass and preparation method thereof that emits white light under exciting of 346nm～380nm); Solve the aberration problem that causes because of fluorescent material is different with the blue chip luminescent lifetime, avoided the complicated coating processes of conventional fluorescent powder simultaneously.

Said ion Ce, Tb are trivalent ion, and Mn is a divalent ion, and Eu is divalence or trivalent ion.
Take by weighing corresponding oxide compound, muriate and carbonate according to said glass ingredient, fully ground and mixed is even, high temperature melting under the reducing atmosphere condition then, and last moulding annealing obtains the glass that emits white light;
Said glass melting temperature is 1550～1600 ℃, and melting time is 2～3h, and annealing temperature is 550～600 ℃, and annealing time is 2～3h.
The hydrogen in the said reducing atmosphere and the volume ratio of nitrogen are 2: 98～10: 90.
Beneficial effect of the present invention is embodied in:
The present invention mixes and interparticle transmission ofenergy effect realizes three primary colours white light emission efficiently through different kinds of ions altogether, has overcome that existing White-light LED chip and fluorescent material life-span do not match and the aberration and the color developing problem that cause; Owing to directly prepare fluorescent glass, not only ion doping concentration is high simultaneously, and luminosity is high, has also avoided the complicated coating processes of fluorescent material.
Fluorescent glass preparation technology of the present invention is simple, with low cost, environment friendly and pollution-free, has good calorifics, physics, chemicalstability, is expected to be used to make the novel white-light LED device based on ultraviolet excitation.
