Luminescence properties of rare earth complexes bonded to novel mesoporous spherical hybrid materials

YVO4:Eu3+ phosphors have been widely used in optoelectronic integration fields of its chemical and thermal stability. However, the excitation spectrum band of VO43− is too narrow for high-efficiency luminescence, restricting its further development. Herein, flower-like and linear-like YVO4:Eu3+ hollow mesoporous spheres were synthesized and connected with Eu organic ligand, to obtain a new hybrid luminescent material. The characterization shows that the pores of microspheres are in size of about 2–50 nm, sticked with regular morphology, well crystallized, and in uniform distribution. The emission intensity of hybrid luminescent material is higher than that of single YVO4:Eu3+ and single Eu complexes realizing the purpose of mutually reinforcing luminescence. This paper provides a new idea to connect rare earth complexes for a new non-silicon-based mesoporous spherical matrix.
