Abstract: We present a new glass able to produce ultra-broadband yellow fluorescence. The luminescence system is Ce3+ doped low silica calcium aluminosilica glass excited by blue light emitting diode (LED). The glass is prepared by the conventional melting process. We analyze the luminescence properties of the samples by measuring their absorption spectra, excitation spectra, fluorescence spectra. Furthermore, we study the influence of excitation wavelength on the fluorescence intensity and peak wavelength. The doped glass combined with blue LED to obtain the white lighting is achieved. Besides we calculate the Commission Internationale de I'Eclairage chromaticity coordinate. Therefore these glasses have large potentials to be used as white lighting phosphor materials.
