Upconversion luminescence and energy transfer in the fluorophosphate glasses with low phosphate content doped with Tm3+ and Yb3+ions
We report an experimental observation of the upconversion in fluorophosphate glasses doped with different concentrations of Tm3+ ions (from 1020 to 1015 ion/cm3) and a constant content of Yb3+ ions (1021 ion/cm3) when pumped by a diode laser with a wavelength of 975 nm with a change in the pumping p...
