Zusammenfassung:The invention discloses a manufacturing method of laser display green fluorescent powder. The manufacturing method comprises the steps of burdening, primary charging, primary reduction firing, primarypowder selecting and sieving, secondary charging, secondary reduction firing, secondary powder selecting and sieving, water dispersing and sieving, water washing and dewatering and powder drying andsieving. According to the invention, the defect of low brightness of the green light-emitting fluorescent powder for laser display on high-power laser display or laser projection is overcome by adopting a new charging method and a two-time reduction firing method; and the green light-emitting fluorescent powder for laser display has the advantages of high brightness, purer light-emitting color ofthe fluorescent powder, full fluorescent powder particles and more uniform particles. 本发明揭示了一种激光显示绿色荧光粉的制造方法,本发明由配料、一次装料、一次还原烧成、一次选粉过筛、二次装料、二次还原烧成、二次选粉过筛、分散水筛、水洗去水、干燥筛粉组成。本发明通过采用新的装料方法和两次还原烧成方法来解决激光显示用绿色发光荧光粉在大功率的激光显示或激光投影上存在亮度
