摘要:
采用热注射法合成了绿色荧光的无铅铜基钙钛矿Cs3Cu2Cl5颗粒,通过对其结构、形貌和荧光性能等方面进行表征,研究了不同的合成条件对Cs3Cu2Cl5钙钛矿颗粒的光致发光量子产率(Φ)、寿命及环境稳定性的影响。结果表明,在反应温度为150 ℃条件下合成的Cs3Cu2Cl5钙钛矿颗粒具有最高的光致发光量子产率,且在第4周时达到最高值,约为43.5%,荧光寿命约为95 μs,在空气中保存1个月后仍保持原有的晶体结构和良好的荧光性质,显示出良好的稳定性。
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, morphology, and fluorescence performance. The result showed that the Cs3Cu2Cl5 perovskite particles synthesized 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.
