This layered perovskites exhibit good film coverage as twodimensional perovskites and high emission performance close to three-dimensional organic–inorganic hybrid perovskites. Light-emitting diodes（LEDs） are fabricated by using solution process based on the quasi-two-dimensional layered perovskites. The perovskite LEDs exhibit a sky-blue emission with electroluminescence peak at 491 nm and a low turn on voltage at 2.9 V. The maximum external quantum efficiency reaches 0.015% at brightness of 186 cd/m^2.展开更多

文摘利用污水处理厂未消化脱水污泥,采用二氧化锰为催化剂,磷酸为活化剂,通过微波辐照工艺制备了掺锰污泥活性炭,研究了掺锰污泥活性炭对酸性湖蓝A的吸附效果。实验结果表明,掺锰污泥活性炭对初始质量浓度为30 mg/L的酸性湖蓝A的最佳吸附条件为:吸附时间60 m in,掺锰污泥活性炭加入量4 g/L,溶液pH值7,在此条件下,酸性湖蓝A吸附率达99.4%。对不同浓度的酸性湖蓝A进行了动力学研究,由线性相关系数可知:伪二级动力学方程能很好地描述掺锰污泥活性炭对酸性湖蓝A的吸附过程。说明伪二级动力学模型包含吸附的所有过程,能够更真实地反映酸性湖蓝A在掺锰污泥活性炭上的吸附机理。实验结果为污水处理厂污泥的资源化利用提供了理论基础。
