The doping of europium did not induce any new luminescent centers , but caused the luminescent efficiency of defects to increase greatly . 4 . by changing the rinse times during the synthesis of zns nanocrystallite , the surface state was studied 4通过改变zns纳米晶制备过程中清洗的次数,比较了清洗前后发光强度的变化,分析了自激活发光中心在纳米晶中的分布状况,即自激活发光中心倾向于占据表面格位。
The color of devices is disturbed badly and the luminescent efficiency of devices is degradated because of exciplex ' s emission . the mechanism is investigated in this paper on the formation of exciplex and on the mixing - layer device structure eliminating the exciplex based on rare - earth complex , specially on eu ( dbm ) 3bath and gd ( dbm ) 3bath . it is thought that the exciplex results from the interaction between the singlet excited state of the ligand of electron acceptor material and the ground state of electron donor material 本论文以稀土配合物oel为重点和基础,以eu ( dbm ) _ 3bath和gd ( dbm ) _ 3bath为典型材料,研究了激基复合物的形成和稀土配合物器件中混合层能够消除激基复合物,认为激基复合物是电子受体材料配体能级的单重态与电子给体材料的基态相互作用而产生的。
