AbstractControlled reaction conditions in simple, template-free hydrothermal processes yield Tm-Lu2O3 and Tm-GdVO4 nanocrystals with well-defined specific morphologies and sizes. In both oxide families, nanocrystals prepared at pH 7 reaction media exhibit photoluminescence in ∼1.95 μm similar to bulk single crystals. For the lowest Tm3+ concentration (0.2 % mol) in GdVO4 measured 3H4 and 3F4 fluorescence lifetimes τ are very near to τrad.

Efficiency has been compared of the Bayliss-McRae-Ooshika, Bakhshiev, and cross term methods in evaluation of the effect of medium on electronic spectra of nine indicators of polarity of medium using also the data obtained in gas phase and in perfluorinated hydrocarbons.
