Claim:
1. A light emitting device, comprising: a light emitting diode (LED) chip that emits light of a first wavelength; an encapsulant disposed over the LED chip; and one or more downconverters embedded in the encapsulant, wherein each downconverter includes a quasi-two dimensional quantum nanoplatelet structure that interacts with the emitted light of the first wavelength from the LED chip to produce light of a second wavelength that is longer than the first wavelength, wherein the quasi-two dimensional quantum nanoplatelet structure of the downconverter includes a core material covered by at least one nanoplatelet shell, and wherein the at least one nanoplatelet shell has a length and a width larger than a height, wherein the downconverter includes an on-chip downconverter that is formed as a part of the LED chip.
