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通過(guò)改變zns納米晶制備過(guò)程中清洗的次數(shù),比較了清洗前后發(fā)光強(qiáng)度的變化,分析了自激活發(fā)光中心在納米晶中的分布狀況,即自激活發(fā)光中心傾向于占據(jù)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 本論文以稀土配合物oel為重點(diǎn)和基礎(chǔ),以eu ( dbm ) _ 3bath和gd ( dbm ) _ 3bath為典型材料,研究了激基復(fù)合物的形成和稀土配合物器件中混合層能夠消除激基復(fù)合物,認(rèn)為激基復(fù)合物是電子受體材料配體能級(jí)的單重態(tài)與電子給體材料的基態(tài)相互作用而產(chǎn)生的。
