Pressure Effects on the Optical Properties of LuVO4:Eu3+ Nanoparticles
The effect of hydrostatic pressure (varying up to 110 kbar) at the room temperature on three lines at 594nm, 615nm and 619nm positions in emission spectra and fluorescence lifetime t of the Eu3+ for 0-2 line (5D0→7F2 transition) in LuVO4: Eu3+ nanoparticles was studied. The results showed that the increase of the pressure induced lines red shift towards longer wavelengths for all considered lines with different rate. Also, the fluorescence lifetime τ for 5D0 → 7F2 transition nonlinearly decreased with pressure in the considered pressure range. Line positions and fluorescence lifetime τ, were explained by a model which took into account the effect of high pressure on: refractive index of crystal; compression, polarizability of the crystal and individual ions. Satisfactory agreement between measured and theoretical predicted values with error less than 2% was obtained.
