title: Photoluminescence Properties of SrMoO4:Eu3+, Sm3+ Nanophosphors Prepared by Sol-Gel Method.
abstract: Novel red light-emitting nanophosphors of SrMoO4:Eu3+, Sm3+ were synthesized by a facile sol-gel method. Particles have sizes in the range of 50-80 nm. The structures, morphologies and optical properties of as-prepared products were characterized by means of X-ray diffraction (XRD), transmission electron microscope (TEM) and photo luminescent (PL). The results indicate that the red emission intensity was enhanced significantly with the increase of Sm3+ doping concentrations. When the mole fraction of Sm3+ is 2%, the emission intensity of red light is the strongest. It has been found that the incorporation of R+(Li+, Na+) into SrMoO4:Eu3+, Sm3+ phosphor could lead to a remarkable increase of photoluminescence. Thus, it is considered to be efficient red-emitting phosphors.
