| Abstract: | The article reports the infrared quantum cutting phenomenon of the Er-doped nanophase oxyfluoride vitroceramics (Er(3):FOV). The infrared and visible fluorescence spectra of Er(3):FOV are measured carefully. It is found that the approximate quantum cutting efficiency of the 1543.0 nm 4I13/2→4I15/2 fluorescence, when the 2H11/2 levels are excited, is about 186.28%. The relative nonradiative relaxation rate and spontaneous emission rate and energy transfer rate are calculated. The relative energy transfer dynamics is analyzed. It is found that the {2H11/2→4I9/2, 4I15/2→4I13/2} energy transfer channel, with the rate of 371000 s-1, is the main reason for 2H11/2 energy level to have high quantum cutting efficiency. To our best knowledge, the present article for the first time reports Er(3):FOV to have an effective three-photon infrared quantum cutting excited by visible light and a four-photon infrared quantum cutting excited by near-violet light. |
