Growth mechanism and vibrational and optical properties of SrMoO4: Tb3+, Sm3+ particles: green– orange tunable color

A SrMoO4 series co-doped with Tb3? and Sm3? was successfully prepared by the sonochemical method. The particles were characterized by X-ray diffraction, Raman spectroscopy, field emission gun scanning electron microscopy, UV–Vis spectroscopy and photoluminescence. Changes in SrMoO4: Tb3?, Sm3? morph...
