全无机卤化铅钙钛矿（CsPbX3）纳米晶体（NC）因其非凡的光物理特性而成为极具前景的新一代发光体。然而，由于铅的固有毒性和长期环境稳定性，这些半导体NC的性能受到损害。在这里，我们报告了使用 Ba(SCN)(2) 同时添加 B 位阳离子和 X 位阴离子（拟卤化物）（
All-inorganic lead halide perovskite (CsPbX3) nanocrystals (NCs) have emerged as a highly promising new generation of light emitters due to their extraordinary photophysical properties. However, the performance of these semiconducting NCs is undermined due to the inherent toxicity of lead and long-term environmental stability. Here, we report the addition of B-site cation and X-site anion (pseudo-halide) concurrently using Ba(SCN)(2) (
