The methodology and the software for the analysis of the atomic density modulation underneath the surface of a nanocrystal

, , , , , , , ,
Internal structure of nanocrystals can be extracted from Pair Distribution Function, which is obtained by Fourier transform of the diffraction data. Such a transform, G(r), contains complete information on inter-atomic distances present in the investigated [...]

Precipitant molar concentration effect on the upconversion emission in BaZrO3:Er,Yb nanocrystalline phosphor

, , , , , ,
Strong Blue, green, and red upconversion emission of Er3+ in sub-microcrystalline BaZrO3:(Yb3+Er3+) is observed. Powder samples were obtained by a facile hydrothermal process at 100ºC with different water to ethanol solvent ratios. The as synthesized [...]
