Abstract
Embodiments of the present application relate to the use of quantum dots mixed with spacer particles. An illumination device includes a first conductive layer, a second conductive layer, and an active layer disposed between the first conductive layer and the second conductive layer. The active layer includes a plurality of quantum dots that emit light when an electric field is generated between the first and second conductive layers. The quantum dots are interspersed with spacer particles that do not emit light when the electric field is generated between the first and second conductive layers.
