Abstract

Intense multi-peak warm yellowish-white fluorescence emissions of Dy3+ are exhibited in alkaline-earth borate glasses under the excitation of a blue laser. The net emission power and net emission photon number are identified to be 498.23μW and 14.28 × 1014cps, respectively, and the quantum yield is as high as 23.10% in 2.0wt% Dy2O3 doped alkalineearth borate glass under the excitation of a 453nm blue laser with 14.13mW power. Anticipation of fluorescence color reveals that white luminescence can be achieved when the intensity ratio between residual laser light and Dy3+ emission reaches the appropriate range. By the introduction of Ce3+, the excitation wavelength range and the emission intensity of Dy3+ in alkaline-earth borate glasses are expanded to UVB region and improved by a maximum sensitization factor of 38.2, respectively, demonstrating the utilizability of a UV pumping laser for Ce3+-Dy3+ codoped alkaline-earth borate glasses. Efficient fluorescence emission and realizable white lighting in Dy3+ doped alkaline-earth borate glasses under the laser excitation will promote the development of laser illumination devices.
