Abstract
Excitation spectrum of M2MgSi2O7: Eu2+ was composed of two broad bands centered around 310 and 395Â nm, respectively, in which the latter belonged to 4fâ5d transitions of Eu2+. It was found that the introduction of Zn2+ into Ba2MgSi2O7: Eu2+ effectively increased its emission intensity without changing the position of emission peak. A further Eu2+ and Ce3+ co-doped pyrosilicate phosphor was found to be an efficient phosphor excited by long UV light and emitted in blue around 438Â nm, which was originated from the 5d to 4f transition of Ce3+ ion in M2MgSi2O7: Eu2+, Ce3+.
