Abstract: The present invention is related to a light emission or a luminescent material and applications thereof. The said material comprises a spherical core, a spherical shell deposited at outer surface of the spherical core, and further a rod shell deposited at outer surface of the spherical shell. The said spherical core comprises Indium phosphide particle with substantially spherical appearance or condition. The said spherical shell comprises Cadmium selenium deposited at outer surface of the spherical core with corresponded spherical appearance or condition. The rod shell comprises cadmium sulfide deposited at outer surface of the spherical shell with its structure extended in lengthwise longer than crosswise to a rod appearance or condition. The luminescent material provided by the present invention has a Type II NCs structure using cadmium selenium as the spherical shell to emit near-infrared light. The present invention provides InP/CdS/CeSe in core/shell/shell structure as luminescent material which has extra-broadband VIS-NIR emitting abilities.

Abstract: A nanoparticle capable of loading and releasing active constituents includes many mesopores with a large pore size and can be produced by one-step synthesis. The nanoparticle has a BET surface area over 100 m2/g and an average pore size over 1 nm that can load and release a large amount of active constituents quickly to improve the performance and applicability of related slow release carriers. In addition to its application in the field of drug-loaded contact lenses, the properties of such nanoparticle can be applied for releasing other active constituents or drugs, and used for the treatment of human body or even for the release of environmental active constituents.
