Polycrystalline phosphors with a Sr₂Y_8-x-yYb_yTm_xSi₆O₂₆ (x=0.005-0.5, y=0.2,0.3) total formula were synthesized. Nanoluminophor has been obtained from the Sr₂Y_7.695Yb_0.3Tm_0.005Si₆O₂₆ microcrystalline sample by the vacuum electron been evaporation, in the amorphous state, with the ~10.6 nm particle size. It is found, raman spectra undergoing modification by the transition from bulk- to nanosize state. Photoluminescene spectra micro- and nanophosphors are studied. Intensity of the blue emission, by the UV ligth excitation, grows in the x=0.005-0.02 region, with the x increasing. Upconversion photoluminescence (UPCL) spectra of the bulk phosphors and nanosample based on the Sr₂Y_7.695Yb_0.3Tm_0.005Si₆O₂₆ were measurd. At the pumping power around 70.8 mW, by the laser source with the λ=980 nm, thereshold population of the ³F₃ level of Tm³⁺ ions exist. At a power higher 70.8 mW, a sharp increase of the luminescence intensityof the bulk- and nanophosphor occurs. For the ³H₄->³H₆ transition thereshold pumping power absent. This indicates that, pumping, during Yb->Tm energy transer, is a single photon process. Keywords: Photoluminescence, Tm³⁺, Yb³⁺ ions, raman spectra. DOI: 10.61011/EOS.2023.05.56517.55-22
