摘要	Eu3+ and Sm3+ co-doped CaMoO4 microclews have been successfully synthesized via a facile hydrothermal method directly in surfactant-free environment. The as-prepared phosphor present clew-like agglomerates composed of 40 nm nanosheets under the moderated reaction temperature. The red phosphor CaMoO4:Eu3+, Sm3+ can generate a strong absorption line at 405 nm, originating from H-6(5/2) -> P-6(5/2) transition of Sm3+, which is suitable for the emission of the near-ultraviolet light-emitting diodes (similar to 400 nm). Energy transfer between Sm3+ and Eu3+ is detected from the varied photoluminescence spectra with different Eu3+ concentrations and the energy transfer mechanism is clarified via the photoluminescence spectra. When Sm3+ is excited (405 nm), the electron is excited from H-6(5/2) to P-6(5/2), and then relaxed to (4)G(5/2). It jumps from (4)G(5/2) to the lower levels corresponding to the emissions of Sm3+; meanwhile, the transfers from (4)G(5/2) state of Sm3+ ion to D-5(0) state of Eu3+ ion come out. The transition of D-5(1) -> F-7(J) (J = 0, 1, 2) does not appear indicating that the transfer from (4)G(5/2) state of Sm3+ to D-5(0) state rather than D-5(1) state of Eu3+ is the energy transfer pathway.
