A series of color-tunable and white light emitting phosphors BaY2Si3O10:Tm3+,Dy3+ were synthesized by a high temperature solid-state reaction, and their phase structure, photoluminescence properties, and energy transfer processes between rare-earth ions were investigated in detail. Upon UV excitation, white light emission depending on dopant concentrations could be achieved by integrating a blue emission band located at 458 nm and an orange one located at 576 nm attributed to Tm3+ and Dy3+ ions, respectively. In addition, the energy transfer process between Tm3+ and Dy3+ ions was demonstrated to be a resonant type via a dipole quadrupole mechanism. Preliminary studies showed that the phosphor might be promising as a single-phased white-light-emitting phosphor for UV chip pumped white-light LEDs.
