Photoluminescence Spectroscopy Optimizes Perovskite Quantum Dots

Facebook Twitter LinkedIn Email Comments

Perovskite quantum dots could be used to create the next generation of display devices, but first they must be characterized and their emission properties optimized.

STUART THOMSON, EDINBURGH INSTRUMENTS

Perovskite semiconductors have attracted tremendous attention in recent years because of the rapid rise of perovskite solar cell efficiencies — from less than 10% to more than 20% in less than five years — and the potential for the materials to provide low-cost solar power1. The properties that make these materials well suited as absorber layers in solar cells also make them excellent emitters of light, and researchers have shifted their attention toward material optimization for optoelectronic applications such as lasers, lighting, and displays. Of particular interest for display...Read full article
