Abstract

and Tm

co-doped silicate glasses with different contents of Li

were prepared by high temperature melting

which could emit 477 nm blue and 654 nm red light under 980 nm LD pumping. The double logarithmic linear fitting of light emission intensity and pump power show that the probability of Tm

upward transition in up-conversion process increases after the adding of Li

because of the number of electrons populated at

and

energy levels of Tm

increasing

which leads to improving the probability of radiation transition. The infrared spectra and Raman spectra show that the addition of Li

has little effect on phonon energy of the glass substrate

however

the density of phonon states decreases. Finally

the luminescence intensity of Yb

and Tm

in silicate glass is improved by increasing the up-conversion efficiency.
