Study on perovskite lead rivet in-situ growth and fluorescent fiber wet spinning
摘要
Abstract
In order to improve the stability of lead halide perovskite,inhibit lead ion release and reduce the potential biological toxicity threat,lead rivet growth perovskite method was put forward.The lead ion capture process was introduced at the initial stage of crystal growth to solve the problem of lead ion leakage and further improve its stability through the atomic layer deposition strategy,so that it could be safely suitable for the fluorescent wet spinning process.The results showed that the perovskite nanoparticles with the lead rivet strategy could greatly reduce the lead ion emission even under complete dissociation conditions.The fluorescent quantum yield was reached 56.68%,and the lead ion mass concentration of prepared fluorescent fiber for 5 days continuous soaking was only 1.58 μg/L,which could reaching the standard for drinking water.It is considered that the scheme could solve the instability problem of lead halogen perovskite in water,and wet spinning method could be used to prepare perovskite fluorescent fibers with excellent fluorescence stability,chemical stability and biological safety performance.Its breaking elongation was reached 364.72%.It has excellent fiber toughness and weaving performance.关键词
