中文摘要	single-phased ca3si2o7:ce3+,eu2+ phosphor has been successfully prepared by the high temperature solid-state method. the phosphor shows efficient excitation bands from 200 to 400 nm and adjustable emission bands through the energy transfer from the ce3+ to eu2+ ions. the color hues can change from blue towards white ultimately to orange by adjusting the percentage content of doping ions. the investigation reveals that an electric dipole-dipole reaction mechanism should be responsible for the energy transfer from the ce3+ to eu2+ ions. the critical distance was obtained from the spectral overlap in terms of dexter's theory. the developed phosphor ca3si2o7:ce3+,eu2+ exhibits two bands at 440 and 625 nm, respectively, which reveling that it has a great potentiality to be an uv-convertible phosphor for white-light emitting diodes with low color temperature. crown copyright (c) 2013 published by elsevier b.v. all rights reserved.
