One-pot synthesis of high-efficiency one-dimensional perovskite phosphor for warm white LEDs

Abstract

A simple one-pot method was used to synthesize one-dimensional perovskite phosphor, which was characterized using X-ray diffraction, scanning electron microscopy, and photoluminescence spectroscopy. The material demonstrates excellent photoluminescence properties and can emit warm white light with a color temperature of 4710 K and a color rendering index of 84.6. The simple one-pot method makes it easy to synthesize the perovskite phosphor, positioning it as a promising candidate for the production of warm white LEDs. This work provides a detailed analysis of the material's crystal structure and photoluminescence properties.
