1. A monodisperse population of nanocrystals comprising:

  • a plurality of nanocrystal particles, wherein each particle includes a core including a first semiconductor material and an overcoating including a second semiconductor material deposited on the core;

    wherein the first semiconductor material and the second semiconductor material are different;

    wherein the monodisperse population emits light in a spectral range of no greater than about 37 nm full width at half max (FWHM); and

    wherein the monodisperse population exhibits photoluminescence having a quantum yield of greater than 30%.
