摘　　要：采用热注射法合成了绿色荧光的无铅铜基钙钛矿Cs_(3)Cu_(2)Cl_(5)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Cs_(3)Cu_(2)Cl_(5)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Cs_(3)Cu_(2)Cl_(5)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95μs,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。Green fluorescent lead-free copper based perovskite Cs_(3)Cu_(2)Cl_(5)particles were synthesized by hot injection method.The photoluminescence quantum yield(Φ),lifespan and enviromental stability of Cs_(3)Cu_(2)Cl_(5)was studied under different synthesis conditions by characterizing its structure,morphology,and fluorescence performance.The result showed that the Cs_(3)Cu_(2)Cl_(5)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 95μs.After being stored in air for one month,the original crystal structure and good fluorescence properties were still maintained,demonstrating good stability.
