Fabrication, luminescent properties and possible photonics application of Eu:Y2O3 nanoparticles

The Eu³⁺ doped yttria nanoparticles were synthesized by modified Pechini method. Different values of sintering temperature were applied during synthesis process. XRD patterns were taken to examine the structure and estimate the average grains size of obtained nanocrystals. The photoluminescence of obtained powders was measured. Then powders were electrophoretically deposited on ITO-glass slides. Cathodoluminescent spectra of deposited layers were taken and compared. Also the luminescent decay times for ⁵D0→ ⁷F2 were recorded. The influence of sintering temperature on cathodoluminescent and photoluminescent properties of europium doped Y2O3 nanocrystallites and possible application of obtained material will be discussed.
