Abstract
In this paper, Eu doped Y2O3 nanophosphors are prepared at temperature 600oC by the combustion method. X-ray diffraction patterns confirm the formation of pure cubic phase of Y2O3. Electroluminescence of Eu doped Y2O3 has been investigated at different voltages by sandwitching the thick films between the conducting glass plate and aluminium electrode. Conducting transparent electrode has been obtained by depositing SnO2 layers over heated glass substrate. AC voltage of different frequencies was applied and EL intensity was measured with the help of photomultiplier tube. The intensity of EL increases with increasing voltage. PL decay characteristics of the Eu doped Y2O3 nanoparticles in the form of powder were measured.
