Abstract

Organic light entitling diode panel was fabricated using pulsed laser deposition (PLD) method Nd-YAG laser with Q-Switched and 355 nm pulse was used for the PLD. While TPD(N,N'-Di-[naphthaleny]-N, N'-diphenyl-benzidine) was used as a HTL(Hole transport layer), $Alq_3$(8-Hydroxyquinoline, Aluminum Salt) was used as EML/ETL(Emitting Layer/Electron Transport Layer) Organic pellet was fabricated and employed for the PLD method. The absorbances of the organic films were investigated and the measured absorbance values of TPD and $Alq_3$ films was 362 nm and 399 nm, respectively. The turn-on voltage of the OLED panel was 7.5 V and its luminance was $90\;cd/m^2$
