摘要: Intense blue upconversion emission has been observed at room temperature under excitation in the range of 630 - 660 nm a fluoroindate glass doped with 2.5 mol% Tm3+ . The experimental dynamics and power dependence this are well described using photon avalanche model based on mean field approximation.
