摘要

There has been a strong interest in materials with nanometer dimensions because of its immense new applications in sensors, detectors, amplifiers, novel laser sources and emitters. Trivalent-erbium doped Y_2O_3 nanoparticles have been synthesized, and their spectroscopic studies have been carried out using visible laser excitation. The size estimation of the nanoparticles using atomic force microscope will be presented. The upconversion mechanism and laser power studies for the different emissions from Er~(3+) doped nanocrystals will also be presented.
