| titleOfInvention | The method that tungstate red fluorescent powder is prepared based on sol-gel combustion method |
| abstract | The method disclosed by the invention that tungstate red fluorescent powder is prepared based on sol-gel combustion method, specific method is：1) sodium nitrate, magnesium nitrate, gadolinium nitrate, europium nitrate and ammonium tungstate are first weighed respectively, and then weigh five kinds of salt are dissolved in deionized water respectively and are made into five kinds of salting liquids, finally mix to form mixed solution by five kinds of salting liquids；Liquid mixes to form mixed solution；2) weigh citric acid to add in the mixed solution 1) obtained, be agitated to form colloidal sol；Colloidal sol is placed in thermostat water bath and is thermally formed wet gel；Drying obtains xerogel；3) xerogel through 2) obtaining is put into Muffle furnace and calcined, prepare tungstates NaGd 1‑x Eu x MgWO 6 Red fluorescence powder.The method that the present invention prepares tungstate red fluorescent powder based on sol-gel combustion method, can prepare the tungstate red fluorescent powder for showing that stability is good, excitation is high and luminous efficiency is high, be highly suitable to be applied for white light LEDs. |
