摘要

通过将玻璃粉体与发射波长为535~550 nm的黄绿色和660 nm的红色荧光粉混合制备出浆料，采用丝网印刷方法将其印刷在高热导蓝宝石片上，在较低烧结温度下成功制备出具有高显指白光的PiG荧光薄膜(Phosphors in glass flim

PiGF)，并系统地研究了玻璃/荧光粉比例及荧光粉配比对PiGF在色温(CCT)、显色指数(CRI)、发光效率(LE)等方面的影响规律。在12.5 W电功率的蓝光激光(455 nm)激发下，当荧光粉/玻璃质量比例为1∶4、535 nm/660 nm荧光粉质量比为9∶1时，可产生色温为5 500 K、显色指数达92的高显指白光PiGF。该结果表明PiGF在高显指、白光激光照明领域具有极大的应用价值。

Abstract

In this paper

by the way of mixing glass powder with yellow-green(535-550 nm) and red(660 nm)-emitting phosphors

and then coated on a sapphire wafer by screen-printing

the PiG film(Phosphors in glass flim

PiGF) with white light and high CRI is successfully prepared at a lower sintering temperature. The effects of different ratios of glass/phosphor and G/R phosphors(535 nm/660 nm) on PiGF's CCT

CRI

luminous efficiency(LE)

etc

. are systematically studied. The results show that the prepared PiGF can generate white light with a CCT of 5 500 K and a high CRI of 92

when the mass ratios of phosphor /glass powder and G /R phosphor are fixed at 1∶4 and 9∶1

respectively

under the excitation of blue laser diodes(LD

455 nm) with an electric p

ower of about 12.5 W. The results show that PiGF has great practical application in high CRI and white light laser-driven lighting.
