Preparation and Photoluminescence Properties of Er~(3+) -doped Silicate Glasses

摘要

Glasses with different Er~(3+)-doped concentrations were fabricated, and J-0 theory, F-L theory and MC theory have been used to calculate the spectral characteristics of Er~(3+) -doped glasses. The influences of Er~(3+) -doped concentration and the composition of matrix glass material on the physical properties and spectral properties were analyzed and the best doping concentration was obtained. The results confirmed that a strong Near-infrared fluorescence emission at the wavelength of 1534 nm was obtained with the pumped wavelength of 488 nm, 532 nm and 800 nm, respectively, in Er~(3+)-doped cadmium silicate glass. The results obtained have confirmed that the sample was an excellent candidate for preparation of doped photonic crystal fiber material.
