摘要

To enhance the optical performance of ultraviolet (UV)-excited white light-emitting diodes (WLEDs), a novel packaging structure using multi-layered red, green, and blue (RGB) phosphor-in-glass (PiG) was proposed. The RGB PiG was fabricated by screen-printing and low temperature sintering. Comparison experiments between the conventional mixed-RGB structure and proposed packaging structure were conducted. Consequently, Compared with the mixed-RGB PiG, the luminous flux of WLEDs packaged by the multi-layered PiG with the order of R-G-B increases by 8.8% at the driving current of 500 mA, and the corresponding correlated color temperature (CCT) and color rendering index (CRI) are 4065 K and 85.6, respectively.
