Abstract :

Bright yellow fluorescence is observed in a YBr₃:Dy,Er phosphor under 1.31 μm laser diode (LD) irradiation. The intensity of the 660 nm emission (⁴F_9/2-⁴I_15/2 radiative transition of Er³⁺) for the optimum composition of 2DyBr₃-20ErBr₃-78YBr₃ in a bromide phosphor is improved to a level 169 times stronger than that of a chloride phosphor under 5 mW LD excitation
