Abstract

The invention relates to improved green light emitting materials of the formula Me(La 1-a-b-c-d Y a Gd b Lu c Tb d )(Mo 1-x W x ) 2 O8, (La 1-a-b-c-d Y a Gd b Lu c Tb d ) 2 (Mo 1-x W x ) 2O9 and (La 1-a-b-c-d Y a Gd b Lu c Tb d ) 2 (Mo 1-x W x )3O12. These materials have a high lumen equivalent, a fast decay, and a high conversion efficiency which makes them useful for lighting purposes.
