Feature issue introduction: halide perovskites for optoelectronics

Abstract

This joint Optics Express and Optical Materials Express feature issue presents a collection of nine papers on the topic of halide perovskites for optoelectronics. Perovskite materials have attracted significant attention over the past four years, initially for their outstanding performance in thin film solar cells, but more recently for applications in lightemitting devices (LEDs and lasers), photodetectors and nonlinear optics. At the same time, there is still much more to learn about the fundamental properties of these materials, and how these depend on composition, processing, and exposure to the environment. This feature issue provides a snapshot of some of the latest research in this rapidly-evolving multidisciplinary field.

Multilayer phosphor-in-glass packaging for the development in WLED color uniformity

“…The most cost effective and simplest procedure to produce WLEDs is integrating the chromatic lights of blue LEDs, a compound of adhesive gel, and yellow phosphor (Y3Al5O12:Ce 3 ). However, the WLED from this procedure is inadequate for high lighting applications because of its poor thermal performance even compared to others [13,14]. The cause for this incident is defined as the heat generation of phosphor, such  ISSN: 1693-6930 TELKOMNIKA Telecommun Comput El Control, Vol.…”
