摘要： 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. Upon application to for example a diode comprising the hybrid nanomaterial of a single excitation energy value, the hybrid nanomaterial substrate converts the energy value into light emissions that across the variable substrate generates light emissions in white light range. The hybrid nanomaterial is tunable to achieve desired light emitting characteristics of the light emitting structure.

摘要： The present invention relates to low reabsorbing semiconductor nanocrystals having, simultaneously, an emission center core surrounded by at least one absorbing shell capable of absorbing blue or purple light and a protective exterior shell. The emission center core is capable of emitting at least one different wavelength range of light. The low reabsorbing semiconductor nanocrystals demonstrate an absorbance ratio greater than or equal to 10. These low reabsorbing semiconductor nanocrystals can be used in optical applications, some of which can include, for example, light-emitting diodes, solid-state-lighting, solar cells, lasers, and biomedical tags.
