Description
Summary:SrA1204：Eu2＋,Dy3＋ hollow microspheres were successfully prepared through a facile and mild solvothermal co-precipitation combining with a postcalcining process. The structure and particle morphology were investigated by X-ray diffxaction （XRD）, scanning and transmission electron microscopy （SEM and TEM） pictures, respectively. The mechanism for the formation of spherical SrAI204：Eu2＋,Dy3. phosphor was preliminary presented. After being irradiated with ultraviolet （UV） light, the spherical phosphor emitted long-lasting green phosphorescence. Both the photoluminescence （PL） spectra and luminance decay, compared with that of commercial bulky powders, revealed that the phosphors had efficient luminescent and long lasting properties. It was considered that the SrA1204：Eu2＋,Dy3. hollow microspheres had promising long-lasting phosphorescence with potential scale-dependent applications in photonic devices.
