Color-tunable photoluminescence has been realized by constructing Bi3.6Eu0.4Ti3O12/ZnO (BEuT/ZnO) nanorods composite films. The composite films were prepared by a hybrid chemical solution method. Effects of ZnO nanorods on photoluminescence of BEuT were studied. On one hand, the near-band-edge ultraviolet emission of ZnO nanorods can greatly improve the red emission of Eu3+ ions in BEuT, and on the other hand, ZnO nanorods can also produce a strong green deep-energy-level luminescence. Our study demonstrates that the color of photoluminescence in the composite films can be tuned from green to yellow to red, through suitable control of ZnO nanorods. The BEuT/ZnO nanorods composite films with the color-tunable photoluminescence may have potential applications for white light emission and other integrated optoelectronic devices.
