Abstract

Read online

Cs4PbBr6 crystals have been synthesized by an ultrasonication-assisted trace amount polar solvent method. The prepared green Cs4PbBr6 material was found to have high photoluminescence (PL) brightness and 10 ns PL lifetime. The prepared green light emitting device can achieve the maximum brightness of 3.8 × 109 cd/m2, which is nearly 100 times higher than a wick. The white light emitting device based on Cs4PbBr6 crystals has better performance than commercial products, which can cover 32.3% of the color gamut and achieves 107.3% coverage for International Commission on Illumination (CIE)1931 and 84.8% coverage for CIE1976.
