摘要：

Flower-like Mg3B2O6:Eu3+ hierarchical microspheres, with an average diameter of 2.0 similar to 2.5 mu m, were successfully synthesized via a simple precipitation method using poly (vinyl pyrrolidone) as template and followed by a subsequent heat treatment. The structure, morphology, composition and photoluminescence (PL) properties of as-prepared and calcined samples were systematically characterized by XRD, SEM, TEM and PL spectra, respectively. The resultant products presented a strong characteristic of red emission at 612 nm corresponding to (5)D(0 ->)7F(2) of the Eu3+ transition under ultraviolet excitation at 393 nm, which may open a wide door for its applications especially in fluorescent lamps, display systems, and optoelectronic devices. Besides, we demonstrated the morphology, concentration of Eu3+ as well as calcination temperature had a great effect on the PL properties of the microspheres.
