Abstract
A novel single-phased white-light-emitting phosphor Sm3+ doped LiCa3MgV3O12 (LCMV) was developed. The LCMV host was one self-activated bluish-green emitting phosphor, which possessed an efficient excitation band in the 250-400â¯nm wavelength range and showed an intense broadband bluish-green emission with internal quantum efficiency (IQE) of 39%. Doping Sm3+ ions in to LCMV host induced tunable-color emissions, due to the energy transfer from [VO4]3â to Sm3+ ions. Importantly, under 340â¯nm excitation, the LCMV:Sm3+ can emitted bright white light by combining the self-activated luminescence of LCMV host and the red emissions of Sm3+ ions, and the IQE of the white-emitting composition-optimized LCMV:0.01Sm3+ phosphors reached up to 45%. These white-emitting LCMV:Sm3+ phosphors have potential applications in white light-emitting diodes and optical display devices.
