In this study, the laser sintering technique was used to obtain Er/Yb co-doped silica glasses for up-conversion (UC) luminescence for the first time. Further, structural analysis of the glass sample was conducted via XRD, SEM and EDS measurements. Based on the measured absorption spectrum, important spectroscopic parameters including three intensity parameters Ω (t = 2, 4 and 6), theoretical and experimental line strengths, spontaneous transition probabilities, branching ratios and radiative lifetimes, were calculated using the Judd-Ofelt (J-O) theory. The UC properties of Er/Yb co-doped silica glasses were investigated upon the excitation of a 976 nm laser. It has been experimentally confirmed that the green and red UC luminescences corresponding to the radiative transitions of Er: H → I (green), S → I (green) and F → I (red) were achieved. This result is consistent with those of the J-O theoretical analysis. Additionally, the energy transfer mechanism between Er and Yb, which is responsible for the UC process, was discussed based on their dependence on the pump power. The obtained results indicated that the Er/Yb co-doped silica glasses manufactured using the laser sintering technique can be promising for the application of short-wavelength lasers.
