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..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
