Photoluminescent and thermoluminescent properties of low temperature synthesized Nd3+ doped Mg2SiO4 nanophosphors for display and dosimetry applications

Dual substitution of host lattice ions to enhance the luminescence properties of Zn2TiO4:Cr3+ phosphor

“…According to the calculated values of R c of more than 5 Å, the electric multipolar interaction was the main reason for concentration quenching in ZLTN:0.005Cr 3+ . The following formula is used to study the electric multipolar interaction [50–52]: $$$$ \frac{I}{x}=k{\left[1+\beta {(x)}^{\frac{\theta }{3}}\right]}^{-1} $$$$ where, k and β are the constants, I is the emission intensity, and the doping concentration of Cr 3+ is expressed as. When θ is equal to 6, 8, 10, it denotes a dipole–dipole interaction, dipole–quadrupole interaction and quadrupole–quadrupole interaction, respectively [53,54].…”

Controllable synthesis and characterization of Mg2SiO4 nanostructures via a simple hydrothermal route using carboxylic acid as capping agent and their photocatalytic performance for photodegradation of azo dyes

“…7 . The weak absorption band at lower wavelength may be assigned to the metastable states developed between the valence band and conduction band 36 and shows two excitonic absorption peaks at 273 and 352 nm. The absorption peak that occurs at 352 nm is due to the fundamental absorption within the bandgap of this material.…”
