Upconversion luminescence mechanisms in Er³⁺ and Er³⁺/Yb³⁺ doped nanoparticles: dependence on phonon energies and concentrations

Upconversion luminescence, a phenomenon where two or more lower-energy photons are converted into higher-energy emissions, holds significant potential for applications in several fields, including imaging, sensing, security inks, and photonics. Upconversion luminescence mechanisms in Erbium (Er³⁺) a...
