In this study, we introduce a low-melting-point (MP) glass ceramic (GlaC) material which can be used to fabricate a phosphor-in-glass (PiG) with Y3Al5O12:Ce3+ (YAG) phosphor for the realization of high-power white-light-emitting diodes (WLEDs).

Color Converter

We proposed an all-inorganic multi-color converter based on Eu3+-doped phosphor-in-glass (PiG) for high-power white light-emitting diodes (WLEDs). The Eu3+-doped PiG was fabricated by screen-printing and low-temperature sintering a green phosphor into a Eu3+-doped glass matrix, which was prepared by a lead-free and low-melting glass frit doped with Eu3+ ions. When the Eu3+ doping content increases from 0.5 to 5 mol%, the transmittance of Eu3+-doped glass matrix is reduced while the red emission intensity is increased. In addition, with the green phosphor mass ratio of 30%, the Eu3+-doped PiG based WLEDs achieve a warm white light with a correlated color temperature (CCT) of 4496 K and a color rendering index (CRI) of 82 at the driving current of 350 mA. These results indicate that the Eu3+-doped PiG is a promising multi-color converter for high-power WLEDs.
