中文摘要：

以自制的“D-π-D”对称型有机绿色发光分子1，4-双（4’-N，N-二甲基氨基苯乙烯基）萘（简称BMABN）为发光层，在结构为ITO／NPB／BMABN／BCP／Mg：Ag的器件中，研究了空穴阻挡层厚度对器件发光性能的影响。结果表明，空穴阻挡层的增厚使得器件的起亮电压有所增加，但器件的亮度、电流效率和稳定性显著增加。该器件在5V开启，18V电压下亮度和效率分别为2000cd／m^2和0．41m／W。

英文摘要：

The electroluminescence devices （ITO/NPB/emitting layer /BCP/Mg ： Ag） based on 1,4-bis （4-N, N-methylamino styryl） naphthalene as emitting layer have been designed by the energy band matching principle. Current efficiency, power efficiency, brightness and stability of the devices have been enhanced when the thick- ness of hole countercheck layer （BCP） is increased to 60nm in comparison with 30nm. The three-layer＇ EL devices exhibit the maximum brightness of 2100cd/m^2 and the largest power efficiency of 0.41m/W, respectively.
