Description :
The blue light emitting OEt-DPQ organic phosphor based on a pyrazoloquinoline derivatives was synthesized by using the acid-catalyzed Friedlander reaction. The Synthesized organic phosphors were characterized by FTIR, TGA & DTA, UV-vis absorption and emission spectroscopy. The synthesized OEt-DPQ organic phosphor demonstrates emission in blue region at 391 nm in powder when excited at 368 nm. Thermal analysis showed that the good thermal stability upto 301 0C. Because of good thermal stability the synthesized phosphor may be efficiently used as the emitter materials in Organic Light-Emitting Diodes OLEDs.
Hence, the synthesize blue emitting 2-(4-Ethoxy phenyl)-4-Diphenylquinoline (OEt-DPQ) has generated considerable interest owing to their good photoluminescence efficiencies.
