1. A tunable light emitter comprising:
a nanoplatelet heterostructure, wherein the nanoplatelet heterostructure comprises at least two monolayers of a II-VI semiconductor material; and
at least one quantum dot on a first surface of the nanoplatelet heterostructure;
wherein the at least one quantum dot tunes emission of the nanoplatelet heterostructure and the nanoplatelet heterostructure emits in wavelength range from 900 nm to 1500 nm.
