Abstract:

Duo to the unique luminescent property, thermal conductivity and chemical stability, phosphors/glass composite (Phosphor-in-Glass, PiG) has a huge market application prospect as an alternative to silicon-based phosphor converter for conventional white LEDs, as well as a solution to the heat emission, luminous efficiency, quality, glare, lifetime and other technical problems at the same time. Herein, some key scientific topics in terms of PiG materials were analyzed, such as luminescence properties, transparency, mechanical strength, and mass production; the targeted optimization measures were also comprehensively summarized, including preparation methods (tabletting sintering, melt quenching, and film sintering), material composition design, and the structure optimization of phosphor layers. Generally, this review presents the most recent advances of excellent performance PiG materials, and also prospects their research trend.

Key words: white LEDs, phosphor-in-glass, performance optimization, review
