“…XRD results confirmed the crystal phase purity of YV 0.5 P 0.5 O 4 doped derivatives (Figure ). The XRD peaks are broadened and further confirm the structural disorder, as observed earlier. ,, This broadening originates from the size difference between V 5+ (0.36 Å, C.N. 4) and P 5+ (0.17 Å, C.N.…”

In this study, solid-state solutions of yttrium orthovanadate-phosphate with varying concentrations of codopants (Eu 3+ , Bi 3+ ) have been obtained via coprecipitation. An ionic radii mismatch between V 5+ and P 5+ substituents is manifested in broad XRD lines. The sharpening of the XRD lines is observed with increasing bismuth ions concentration in the Eu 3+ codoped YV 0.5 P 0.5 O 4 matrix. The difference in the number of the Stark components for the 5 D 0 → 7 F J transitions indicates changes in the lattice and a number of possible Eu 3+ sites. A thorough, systematic spectroscopic analysis of YV 0.5 P 0.5 O 4 : x mol % Eu 3+ , y mol % Bi 3+ was conducted at room temperature and 5 K. Metal-to-metal energy transfers occurring between Eu 3+ , V 5+ , and Bi 3+ optically active ions have been investigated. Additionally, efficiency of the Bi 3+ -Eu 3+ energy transfer (ET) was calculated.

“…The Er 3+ ion has high luminescence efficiency and an emission peak located in the green and red light regions, which can be used as a source of green and red light [3]. As for the selection of sensitized ions, the Yb 3+ ion is an efficient sensitizer for many rare earth (RE) elements because its absorption region is approximately 976-980 nm [4]. This ion has a large absorption cross section and can transfer absorbed infrared light to Ho 3+ , Tb 3+ , Pr 3+ , and Tm 3+ through an energy transfer process.…”

In this study, a series of well-crystallized Yb3+/Er3+/Tm3+-tridoped Y2O3-ZnO ceramic nano-phosphors were prepared using sol–gel synthesis, and the phosphor structures were studied using X-ray diffraction, scanning electron microscopy, and thermogravimetric analysis. The phosphors were well crystallized and exhibited a sharp-edged angular crystal structure and mesoporous structure consisting of 270 nm nano-particles. All phosphors generated blue, green, and red emission bands attributed to Tm: 1G4→3H6, Er: 2H11/2 (4S3/2)→4I15/2, and Er: 4F9/2→4I15/2 radiative transitions, respectively. Increasing in luminescent centers, weakening of lattice symmetry, and releasing of dormant rare earth ions can enhance all emissions. Er3+ can obtain energy from Tm3+ to enhance green and red emission. These colors can be tuned by optimizing the doping concentrations of the Er3+ ion. The color coordinates were adjusted by tuning both the Er3+ concentration and excitation laser pump power to shift the color coordinates and correlated color temperature. The findings of this study will broaden the potential practical applications of phosphors.
