Synthesis and red emission of Eu3+ doped LaBWO6 nanorods.

Eu 3+ ions doped LaBWO 6 phosphors were synthesized by a facile hydrothermal method. The phase, morphology and luminescence properties of the obtained samples were characterized. The XRD, Raman and IR results showed that the obtained samples have the orthorhombic phase, indicating the doped Eu 3+ will not change the phase of host. The TEM and SEM images showed that the obtained sample have the rod-like morphology. The excitation spectrum showed that Eu 3+ ions doped LaBWO 6 phosphors have excitation bands ranging from the ultraviolet region to blue region. The emission spectra showed that Eu 3+ ions doped LaBWO 6 phosphors emit dominate red light under 281, 394 and 464 nm excitations. And the decay of the red emission fitted well with the double exponential function. [ABSTRACT FROM AUTHOR]
