| titleOfInvention | White light LEDs single-substrate white launches fluorophosphate fluorescent material and preparation method |
| abstract | The invention discloses a kind of white light LEDs single-substrate white and launch fluorophosphate fluorescent material and preparation method thereof.Wherein, the chemical representation of fluorescent material is Ba 3 GdNa(PO 4 ) 3 F:xEu 2+ , wherein, x is 0.001～0.10.Its preparation method is to weigh corresponding oxide spinel barium, ammonium dihydrogen phosphate, Gadolinia., sodium fluoride and europium oxide by the stoichiometric proportion of above-mentioned chemical formula, after each raw mill is uniformly mixed so as to obtain mixture, again mixture is sintered 2～7 hours in high temperature furnace under the conditions of reducing atmosphere and 1250～1350 DEG C, be then cooled to room temperature and obtain described single-substrate white transmitting fluorophosphate fluorescent material.Gained fluorescent material of the present invention excites lower transmitting white light in ultraviolet and purple light chip, there are two emission peaks, lays respectively at 470nm and 650nm.This fluorescent material good dispersion, uniform granularity, chemical stability are good and luminous efficiency high, and its excitation band covers ultraviolet, purple light and blue region, can be as ultraviolet and purple LED single-substrate white emitting phosphor. |
