Provided is a light emitting device that includes a substrate; a first electrode formed by a first electrically conductive layer arranged over the substrate; an active light emitting layer arranged over said first electrically conductive layer, and that includes a host matrix and light emitting quantum dots embedded there within; and a second electrode formed by a second electrically conductive layer arranged over the active light emitting layer. The host matrix has charge carrier supplier quantum dots blended with the light emitting quantum dots, forming a binary blend where the charge carrier supplier quantum dots are made and arranged to supply charge carriers to the light emitting quantum dots, and wherein the light emitting quantum dots are made and arranged to accept the supplied charge carriers. Also provided is a spectrometer having the LED and a down-converting film for a LED.
