Fundamental understanding of white light luminescence in lead-free double halide perovskites for application in white LEDs

Research question

This project aims to develop a better understanding of structure-property relationships in luminescent lead-free double halide perovskites, with a view towards their application in phosphor-converted light emitting diodes (LEDs). Crucially, we address the question what determine the strong decrease in luminescence as a function of increasing temperature, commonly known as thermal quenching of luminescence, as observed for these types of materials. Based on this new insight, we hope to develop design principles for better performing lead-free double halide perovskites for the specific application in white lighting.

Sustainability aspects

This project will contribute to the development of white LEDs that consume less electricity, are built of safe and abundant elements, and are cheaper than those LEDs currently on the market. Is supports several of the Sustainable Development Goals.
