摘要：

The aim of this work is to measure the photoluminescence of the Disperse Blue 79 (DB 79) deposited as thin films and study its morphological properties by the mean of the Atomic Force Microscopy technique in order to apply it as an Organic Emitting Light Diode (OLED). The films were prepared by the mean of the home-made Physical Vapor Deposition apparatus in a high vacuum on BK7 glass substrates. The linear optical properties were studied by photoluminescence and decay time spectra. The photoluminescence was measured in a broad ranged from 25 to 300 K in a high vacuum, while the decay time technique was investigated to measure the studied sample's life-time in real time. Obtained results confirm homogeneous morphology and good optical quality of investigated organic azobenzene dye. These results allow the DB 79 dye to be used for the first time in production of the Organic Light Emitting Diodes (OLEDs).
