Abstract :High-priced coating devices limit producing electronic devices and circuit applications widely in laboratories. Simply In this study spin coating technique was used to create surface thin films. Also with this method, an OLEDinsert ignore into journalissuearticles values(Organic Light Emitting Diode); device was practically produced. OLED device includes mainly HTLinsert ignore into journalissuearticles values(hole transfer layer);, fluorescent layerinsert ignore into journalissuearticles values(light-emitting layer);, and an ETLinsert ignore into journalissuearticles values(electron transfer layer);. Light-emitting layers in OLED experimental studies are frequently done with commercially produced expensive fluorescence polymers. As an example, MEH-PPV insert ignore into journalissuearticles values(Poly[2-methoxy-5-insert ignore into journalissuearticles values(2’-ethyl-hexoxy);-1,4-phenylenevinylene]);, Alq3 insert ignore into journalissuearticles values(Tris-insert ignore into journalissuearticles values(8-hydroxyquinolinato); aluminum); are mostly known and used fluorescent semiconductor polymers. Alternative to these fluorescent polymers, three different produced quinoline ligand products has fluorescent feature were evaluated. After comparing the fluorescence yields of the produced three complexes, it was seen that 5,7-dibromo-8-hydroxyquinoline has the highest fluorescent response from the others. OLED device production was done with a commercial MEH-PPVinsert ignore into journalissuearticles values(commercial); fluorescent product, and produced insert ignore into journalissuearticles values(5,7-dibromo-8-hydroxyquinoline);. Designed OLED device illumination spectrum was found in the UVinsert ignore into journalissuearticles values(ultraviolet); region. It was concluded that this quoniline product can use as a fluorescent material to produce an OLED device.
