摘要: A SrMoO4 series co-doped with Tb3+ and Sm3+ was successfully prepared by the sonochemical method. The particles were characterized X-ray diffraction, Raman spectroscopy, field emission gun scanning electron microscopy, UV–Vis spectroscopy photoluminescence. Changes in SrMoO4: Tb3+, morphologies observed from an orderly growth of particles. mechanism particle proposed, indicating a hierarchical evolution morphologies. changes emissions evaluated effect dopants their concentrations. Emissions white, green orange according to chemical composition samples. 1% Sm samples showed excellent results for CRI (79%) LE (> 310 lm/Wopt), thus material potential efficient white light emission.
