Paper Abstract

Five samples of ZBLAN:Er3+ (Er3+ concentration: 500 ppm, 5000 ppm, 1 mol%, 1.5 mol%, 3 mol%) were fabricated and their optical and thermal parameters were analyzed. The up-conversion processes of the green, red and blue emission bands were investigated under 970 nm pump. The green at 525 - 545 nm and red at 654 - 665 nm radiation transitions are due to two photons absorption; and the blue generation is maybe responsible for the single excited state absorption at 545 nm from the 4I13/2 level. In our experiment, the 1.5 mol Er3+% in ZBLAN:Er glass sample is the optimum doping-concentration that generates green emission under 970 nm LD pump, because its luminescence intensity almost is quasi-linear with working current in 10 mA range from 230 to 240 mA in comparison with other samples.
