Study of the high pressure effect on nanoparticles GdVO4: Eu3+ optical properties

Abstract

This study considers the effects of hydrostatic pressure on the line position and fluorescence lifetime for D-5(0) F-7(2) transitions in GdVO4: Eu3+ nanocrystals. The results indicate that the pressure induced the red shift toward longer wavelengths for all the considered lines with different rate. The fluorescence lifetime nonlinearly decreases with pressure in the considered pressure range. High pressure induced the fluorescence lifetime that can be explained with a simple theoretical model. The measured line position and are in a satisfactory agreement with the theoretical calculations.
