Abstract

Nanocrystalline Nd:YAG and Nd:YbAG have been synthesized via ammonium bicarbonate co-precipitation methods with doping concentration of 0.5 at.% ~ 4.5 at.%. Different pH and temperature factors were investigated with methods of TG-DSC, XRD, IR, LRS etc. to search optimal formation conditions. A complete transformation was observed at 1100 oC / (pH=8) and 1000 oC / (pH:8-9). The SEM revealed fine dispersion and particle sizes of both. Best performance of nanocrystalline Nd:YAG were achieved when doping with 3 at.% and the novel nanocrystalline Nd:YbAG have no concentration quenching in same range which were learned by results of fluorescence spectrum test..
