A study and characterization of photophysical properties of fluorene derivative thin flim

An emissive layer, fluorene derivative, was performed for organic light-emitting device properties. The preparation of fluorene derivative thin film by spin coating and convective technique was studied the band diagram of thin films which its properties out as the energy gap (Eg). UV-Visible spectrophotometer has been used to investigate the thin film properties. The results indicate spectacular property which occurs in the optical properties, fluorescence in thin film and luminescence as a green light in device that it could be applied as emissive layer for organic light-emitting diodes (OLEDs) due to the appropriate work function with cathode and anode, aluminum metal and indium tin oxide layer (ITO), respectively.
