摘要: 采用新型的空穴传输材料三苯基二胺衍生物聚合物( PD)制成了ITO(氧化铟锡)/PTPD/Alq3 (8-羟基喹啉铝)/Mg:Ag异质结电致发光器件,考察了其电致发光特性.结果表明,当Alq 厚度很薄(小于或等于10nm)时,器件仅为 PD层特征发光;当Alq3厚度达到50/lm时,器件仅为Alq3层特征发光.将所制得的器件与典型的ITO/TPD/AIq3/Mg:Ag器件进行了比较,发现稳定性明显提高,其原因是PTPD的热稳定性高、成膜质量好.

Abstract:

ITO/PTPD/Alq3/Mg:Ag heterostructure electroluminescent diode was fabricated by using a novel poly-TPD as the hole transport material,and its electroluminescent properties was investigated.The results indicate that only the intrinsic emission of PD(poly-TPD)is obtained when Alq3 layer is very thin(not more than 10 nm),and that only the intrinsic emission of Alq3 is obtained when the thickness of Alq3 layer is up to 50 nm.Moreover,the fabricated diode is of an improved stability due to the excellent thermal stability and film quality of PTPD,as, compare with the typical ITO/TPD/Alq3/Mg:Ag device.
