合成温度对Cs3Cu2Cl5荧光性能及稳定性的影响
Effect of synthesis temperature on the photoluminescence and stability of Cs3Cu2Cl5
摘要
Abstract
Green fluorescent lead-free copper based perovskite Cs3Cu2Cl5 particles were synthesized by hot injection method.The photoluminescence quantum yield(Φ),lifespan and enviromental stability of Cs3Cu2Cl5 was studied under different synthesis conditions by characterizing its structure,morphol-ogy,and fluorescence performance.The result showed that the Cs3Cu2Cl5 perovskite particles synthe-sized under the reaction temperature of 150 ℃ had the highest photoluminescence quantum yield,and reached the highest value about 43.5％in the fourth week,with the fluorescence lifetime about 95 μs.After being stored in air for one month,the original crystal structure and good fluorescence properties were still maintained,demonstrating good stability.关键词
