摘要
以聚氧化乙烯为聚合物添加剂,采用不同比例的甲基溴化铵和溴化铅(Ⅱ)制备了复合材料薄膜,研究了不同比例对薄膜形貌、结晶性、光物理以及电致发光特性的影响,并探讨了复合材料中聚合物添加剂种类和含量对其特性的影响。结果表明,多层结构器件的最大发光效率(6.4 cd·A
-1)比单层结构器件的最大发光效率得到了显著提高。
Abstract
With polyethylene oxide as a polymer additive, the composite films are prepared out of the solutions with different ratios of CH3NH3Br and PbBr2 (Ⅱ). The influences of different feeding ratios on the morphology, crystallinity, photophysics and electroluminescence properties of the films are studied. The effects of the species and contents of polymer additives are further investigated. The results show that the multilayer structure devices have the maximum luminance efficiency of 6.4 cd·A
-1, much higher than that of the single-layer devices.
