Paper Abstract
In this work we have developed white-emitting phosphors that can be activated at long UV wavelengths. A blend of EuAlO3:Eu3+ (red), EuAlO3:Eu2+ (green) and Y2SiO5:Ce3+ (blue), prepared by the combustion synthesis technique, yielded a white luminescence spectrum that can be stimulated with long wavelength UV photons. White emission from rare earth doped single-host yttrium oxyorthosilicates, has been also investigated. (Y0.9625Ce0.0075Tb0.03)2SiO5 exhibits an efficient, nearly D65, white emission with chromaticity x=0.225, y=0.320 due to a non-radiative (inductive) energy transfer between Ce3+ and Tb3+.
