Abstract
The new phosphor calcium magnesium chlorosilicate, codoped with Eu2+ and Dy3+, was synthesized with the help of the high temperature solid state reaction in reducing atmosphere. The excitation and emission spectra were very similar to that of Ca8Mg(SiO4)4 Cl2:Eu2+, and the Dy3+ concentration influenced the emission intensity of this phosphor. The intensity of Eu2+ and Dy3+ codoped CMSC was stronger than that of Eu2+ singly doped CMSC. The emission spectrum of the Dy3+ ion overlapped the absorption band of the Eu2+ ion, indicating that an energy transfer from Dy3+ to Eu2+ took place in CMSC:Eu2+, Dy3+ phosphor. The mechanism of the energy transfer from Dy3+ to Eu2+, in this phosphor, might be resonant energy transfer.
