Quantum yield and energy transfer in up-conversion SrGd2O4:Yb, Er nanoparticles obtained via sol-gel assisted combustion
(Journal of Luminescence, 2023)
Nanopowders of up-conversion SrGd2O4 orthorhombic (Pnma) phase co-doped with different Yb3+ (1, 2.5 and 5 at%) and constant Er3+ (0.5 at%) ions were successfully prepared via sol-gel assisted combustion. Rietveld refinement ...
