“…Peaks at 615 and 619 nm ( 5 D 0 → 7 F 2 transition) are electric dipole transition, while 593.7 and 594.2 nm ( 5 D 0 → 7 F 1 transition) are magnetic dipole transitions (12,13). The 5 D 0 → 7 F 1 , 5 D 0 → 7 F 3 , and 5 D 0 → 7 F 4 transition lines are henceforth neglected because they are disturbed by the sensor (SrFCl:Sm 2+ ) fluorescence.…”

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.

Ferroelectric BaTiO3 became a multifunctional material via doping of lanthanide ions (0.3 mol% Er(3+)/3.0 mol% Yb(3+)) and subsequently upconversion luminescence was enhanced by incorporation of Zn(2+) ions. Upconversion luminescence of BaTiO3:Er(3+)/Yb(3+) perovskite nanophosphor has been studied using 800 and 980 nm laser excitations. The emission dynamics is studied with respect to its dependence on input power and external temperature including lifetime. Based on time-resolved spectroscopy, it is inferred that two types of Er(3+) sites are present in the barium titanate lattice. The first one is a short lived component (minor species) present at 6-coordinated Ti-sites of low symmetry while the second one is a long lived component (major species), present at 12-coordinated Ba-sites with high symmetry. The influence of the introduction of Zn(2+) ions on the lifetime of (4)S3/2 and (4)F9/2 levels of Er(3+) ions is also investigated. Enhanced temperature sensing performance (120 K to 505 K) of the material is observed using the fluorescence intensity ratio technique, employing the emission from the thermally coupled, (2)H11/2 and (4)S3/2 energy levels of Er(3+) ions. The defect luminescence of the material is also found to increase upon Zn-doping.

“…The emission spectrum (Fig. 3, right) of S2 sample is composed of a group of peaks at 595, 617, 642 and 701 nm, which correspond to 5 D 0 -7 F J (J¼ 1, 2, 3, 4) transitions of Eu 3 þ ions [15,16]. The strongest peak is located at 595 nm due to 5 D 0 -7 F 1 transition of Eu 3 þ ions.…”
