In this paper, a broad emission band from Eu2+-doped OH− free calcium aluminosilicate glass is reported. By changing the excitation wavelengths,the results showed it is possible to tune the emission from green to orange, what combined with the scattered light from the same blue LED used for excitation, provided a color rendering index of 71 and a correlated color temperature of 6550K. Our preliminary tests indicate this material as apromising phosphor towards the development of smart lighting devices.
