    Abstract

    The luminescence and excitation spectra from ultra-violet, visible to infrared and fluorescence lifetime of Er3+ doped tellurium glass are measured. It is found that the excitation spectra of 1532 nm infrared light and 550 nm visible light are very similar in peak shape and peak wavelength. When the concentration of Er3+ ions increases from 0.5% to 10%, the visible luminescence and excitation spectra intensity decrease, and those in infrared increase. The lifetime curve exhibits obvious energy transfer phenomena. Results show that the observed phenomenon is near-infrared quantum cutting luminescence. The up-limits of near-infrared quantum cutting efficiency of two-photons, two-photons, three-photons, three-photons corresponding to 4I9/2, 4F9/2, 4S3/2, 2H11/2 states are respectively 193.8%, 184.8%, 277.9%, 272.6%.
