A novel approach has been proposed to realize enhanced near-mid infrared emission in Ce3+ and Tm3+ co-doped oxyfluoride glasses excited at different wavelengths, whereby Ce3+ absorbs the photons in ultraviolet region and transfers the energy to Tm3+, while Tm3+ converts the energy in visible and near infrared region into near-mid infrared region. For the purpose to achieve efficient near-mid infrared emission, ligand field theory has been adopted to optimize the glass host composition. The excitation, emission, time-resolved emission spectra and fluorescence decay curves have been measured to investigate the energy transfer (ET) from Ce3+ to Tm3+ and the generation mechanism of near-mid infrared emission. This approach will be of reference value for designing the gain medium of the near-mid infrared laser excited directly by the sunlight.
