Abstract

3D microarchitecture Sr3V2O8:xSm3+ phosphors have been fabricated via hydrothermal method, and their crystalline phase, morphology, and luminescent properties were investigated. The SEM results indicate that the broom- and flower-like micorarchitecture is self-assembled by numerous nanorods. The luminescent properties of Sr3V2O8:xSm3+ samples suggest that the most intense emission is located around 648 nm due to 4G5/2 → 6H9/2 transition of Sm3+. The emission intensity is enhanced with Sm doping and the related mechanism is discussed in detail.
