The nanocrystalline ZrO2 : Pr3+ and ZrO2 : Pr3+, Sm3+ powders with room temperature sharp characteristic emissions were prepared by coprecipitation method. Luminescence properties of nanocrystalline ZrO2 : Pr3+ with different sintering temperatures and doping concentrations were studied. The energy transfer between the nanocrystalline ZrO2 host and the(More)
Y0.96 Er0.02 Yb0.02)O3 nanocrystals of 10 and 40 nm average particle size were prepared by combustion method. And bulk materials of the same components were obtained by annealing at 1 200 degrees C. X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectra, transmission electron microscope (TEM), and scanning electron microscopy (SEM) were used to(More)
