Abstract

Wéve studied the influence of doping concentration with UV-Vis absorption spectra analysis and their photoluminescence (PL) characteristics. With applying variations of doping concentration, co-doped organic solid films were prepared. The host material was Tris-(8-hydroxyquinoline) aluminum and the two dopants were N, Ǹ-dimethyl-quinacridone and 1 O-(2-Benzothiazolyl)-2, 3,6,7- tetrahydro-1 , 1 ,7,7,-tetramethyl-1 H,5H, 11 H-[1 ]benzopyrano[6,7,8-ij] quinolizin-1 1-one. The PL characteristics showed its dependence on doping concentration, as doping concentration changes the PL changed also, and it showed certain trend in intensity. The trend was in agreement with previous study of single-doped and co-doped organic light-emitting diode (OLED) in previous works. This shows PL could be an effective way for estimate the performance of doped OLED.
