A method of synthesizing a hybrid nanomaterial substrate for use in a light emitting structure is provided comprising the steps of: (a) defining one or more light emission characteristics for the light emitting structure; (b) selecting a nanocrystal and a compatible light emitting molecule; and (c) based on the light emission characteristics synthesizing a hybrid nanomaterial substrate by selectively varying the size of the nanocrystals in the substrate, and selectively bonding the light emitting molecules to surfaces of the nanocrystals, thereby synthesizing a nanomaterial structure that is operable to define a single illuminating entity operable upon application of a single excitation energy value to generate light emissions consistent with the light emission characteristics. A novel hybrid nanomaterial is also provided consisting of a nanocrystal-luminescent molecule structure defining a single illuminating entity with light emission affecting structural characteristics that vary across surfaces defined by the nanocrystals based on (a) selective variability of the size of the nanocrystals; and (b) selective variability across the substrate of the concentration of the luminescent molecule bonded to surfaces of the nanocrystals.
