Ni{sup 2+}-doped new silicate glass-ceramics for superbroadband optical amplification
- College of Materials Science and Engineering, China Jiliang University, Hangzhou 310018 (China)
Transparent Ni{sup 2+}-doped new La{sub 2}O{sub 3}-Ga{sub 2}O{sub 3}-Al{sub 2}O{sub 3}-SiO{sub 2} (LGAS) glass-ceramics (GC) embedding {beta}-Ga{sub 2}O{sub 3} nanocrystals was prepared. Upon excitation at 970 nm, an emission band at around 1200 nm was observed originating from the {sup 3}T{sub 2}({sup 3}F){yields}{sup 3}A{sub 2}({sup 3}F) transition of Ni{sup 2+} in distorted octahedral sites. Effects of both heat-treated temperature and doping content on the luminescent properties were also studied. The results revealed that a concentration quenching of the luminescence occurs as the molar ratio of Ni{sup 2+} exceeds the optimum value. The superbroadband near-infrared (NIR) emission from Ni{sup 2+}-doped new GC can be as host materials for a broadband optical amplifier.
