Abstract

Absorption spectra, emission spectra of nanoized erbium implanted mesoporous silica functionalized with and without bis (perfluoromethylsulfonyl) amine as ligand were studied. Luminescence with high intensity has been obtained. The Judd-Ofelt strength parameters Ω_t(t = 2, 4, 6) were calculated as Ω₂ = 1.88 × 10^-20 cm², Ω₄ = 5.45 × 10^-20 m² and Ω₆ = 3.11 × 10^-20 cm, respectively. Oscillator strength, spontaneous emission probability, branching ratio and emission lifetime of each energy levels of Er³⁺ were given. The peak intensity of emission spectra varying with the pump power was discussed. Stimulated emission cross section (σ_em = 10.9 × 10^-21 cm²) was calculated and compared with that of other host materials.
