A New Red Emitting Phosphor Mg2SnO4: Eu
Mg2SnO4 was adopted as the host material of a new red emitting phosphor. Lumin-escence properties of the europium-doped magnesium tin oxide prepared by the low temperature solid state reaction were investigated under 395nm excitation. Under 395 nm excitation, the Mg2SnO4: Eu phosphor exhibits novel red emission at about 613 nm which is assigned to the 5D0 → 7F2 electric – dipole transition. Furthermore, the emission transition 5D0 → 7F2 has been found to be more prominent over the normal orange emission transition 5D0 → 7F1.
