摘要：

Bright visible fluorescence was emitted from Er3+-doped halide phosphors and ErX3 (X=Br, I), under 1.5 mum laser diode (5 mW) excitation. While green fluorescence was predominant with chloride (BaCl2:Er) and bromide (YBr3:Er), yellowish fluorescence was observed with iodide (YI3:Er) and fluoride (YF3:Er). The 550 nm green fluorescence intensities for the chloride, bromide and iodide were, respectively, 43, 10 and 2 times greater than that of conventional fluoride. The excitable wavelength region around 1.5 mum narrowed and the excitation peak shifted toward a longer wavelength with a decrease in the ligand field strength or in the matrix phonon energy.
