The present invention relates to a light-emitting device including a light source, a first light-emitting material spaced apart from the light source, and at least one additional light-emitting material. The first light-emitting material includes low reabsorbing semiconductor nanocrystals having an emission-center core, an exterior protective shell, and at least one inner light-absorbing shell. The device is useful for efficiently producing white light having a high color rendering index. |
