Rare earth activated nanosized oxide phosphors: synthesis and optical properties

摘要: Gd 2 O 3 :I Eu and (Gd,Y) : nanocrystals were prepared by the glycine assist combustion method. The as-prepared products are porous networks from HTEM isolated nanoparticles can be observed after further annealing From luminescence spectra XRD patterns, found to monoclinic. While Y 3+ doped into form complex host, structure changed monoclinic cubic when /Gd is 0.3. More interesting, luminescent intensity of higher than that pure or system Besides pattern, spectra, another powerful evidence in deducing crystal structure, used for analysis.
