摘要:
钙钛矿薄膜的制备方法对发光层的性质及发光二极管(LED)的性能有较大影响。将无机钙钛矿CsPbBr3量子点引入到反溶剂中作为形核位点诱导CH-3NH-3PbI-3薄膜异质形核,然后将该薄膜应用于制备发光二极管。结果表明:应用这种异质形核方法不仅能有效降低CH-3NH-3PbI-3薄膜中晶粒尺寸,提高薄膜质量,限制载流子扩散,且量子点表面多余的配体基团可以对CH-3NH-3PbI-3薄膜中表面及晶界的缺陷产生钝化作用,减小非辐射复合,从而增强载流子寿命和提高辐射复合效率;应用该CH-3NH-3PbI-3薄膜作为发光层制备的LED器件,在低电压下具有较低漏电流,最大外量子效率达到0-17%,相比于基础器件提高了3倍。研究结果将为高质量钙钛矿薄膜及发光器件的制备提供有效途径。
