Green and red up-conversion luminescence spectra related to H-2(11/2),S-4(3/2) -> I-4(15/2) and F-4(9/2) -> I-4(15/2) transitions of trivalent erbium in Er3+/Yb3+ co-doped lead silicate glasses have been studied. The luminescence intensity ratio for bands due to the H-2(11/2) -> I-4(15/2) and S-4(3/2) -> I-4(15/2) transitions of Er3+ was determined and temperature sensitivity parameters were calculated. The maximal temperature sensitivities for Er3+/Yb3+ co-doped glass samples depend critically on rare earth ion concentrations. Based on gathered data it was concluded that Er3+/Yb3+ co-doped lead silicate glasses are promising for optical temperature sensing. (C) 2017 Optical Society of America
