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

This study considers the effects of hydrostatic pressure on the line position and fluorescence lifetime τ for 5 D 0 → 7 F 2 transitions in GdVO 4 : Eu 3+ nanocrystals. The results indicate that the pressure induced the red shift toward longer wavelengths for all the considered lines with different r...

Summary:This study considers the effects of hydrostatic pressure on the line position and fluorescence lifetime τ for 5 D 0 → 7 F 2 transitions in GdVO 4 : Eu 3+ 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 τ nonlinearly decreases with pressure in the considered pressure range. High pressure induced the fluorescence lifetime τ that can be explained with a simple theoretical model. The measured line position and τ are in a satisfactory agreement with the theoretical calculations.
