Transparent nano-glass-ceramics containing rare-earth-doped NaYF_4 nanocrystals (Eu~(3+) single-doped and Yb~(3+)-Er~(3+) co-doped) have been successfully developed for the first time by thermal treatment of precursor bulk glasses obtained by sol-gel technique. X-ray diffraction and high-...
Sol–gel processbull;ZnO nanofiber mats were obtained by sol–gel electrospinning and calcination.•Crystallinity, crystallite size and defects depended on calcination temperature.•Band gap of ZnO nanofibers varied as a function of calcination temperature.•Surface area and pore volume increased as...

Polyester nanocomposites were prepared using sol–gel precursors, prehydrolyzed sols, or nanoparticles in polyester formulations. The different inorganic components were introduced in the early stages of the esterification reaction and a typical polymerization temperature program was applied leading to ...

Zirconia particles synthesized under ambient conditions are frequently amorphous, requiring heat to produce a crystalline phase. Synthesized nanoparticles are generally found in the tetragonal phase. In this article, a room temperature sol–gel synthesis of crystalline sub-10-nm zirconia particles is ...
Pure ZnO films and ZnO nanoparticle dispersed polyvinylpyrrolidone (PVP) films were prepared on a Pyrex glass substrate by solgel dip coating using a zinc acetate precursor. The thin film is extensively characterised for its surface morphology, chemistry, thickness and nanocrystallite size, using ...
