Spectroscopic properties of Sm3+-doped Y2Te4O11 micro-crystals were studied in the 6000–18,500 cm−1 spectral range. Vibrational, electronic absorption, fluorescence and excitation spectra as well as fluorescence dynamics of the Sm3+-doped title micro-crystals are presented and analyzed in detail. A Judd–Ofelt intensity analysis of the absorption spectrum at 300 K has been applied for determination of Ωλ parameters which in turn have been used for calculations of the radiative transition probability factor (A), the fluorescence branching ratios (β), the natural (radiative) lifetime of the 4G(4)5/2 level of Sm3+ and the emission cross-section (σem). An analysis of the non-radiative decay was based on the cross-relaxation mechanisms. The achieved results indicate that the investigated samples are potentially applicable as a 605 and 652 nm laser host as well as an orange phosphor.
