SHAPE-ADAPTABLE AND SPECTRAL-SELECTIVE DISTRIBUTED LIGHT SOURCES USING PASSIVE HOST MEDIUM

摘要

A method of making shape-adaptable and spectral-selective distributed opticalradiation sources, in the wavelength range between UV and mid-infrared, fortherapeutic treatment using passive host medium containing nanocrystals isdisclosed.The spectral output of the distributed optical radiation source is controlledby thenanocrystal size distribution that determines the spectral output offluorescenceradiation originating from these nanocrystals from within the said hostmedium, whichcontains the said nanocrystals, under excitation by an external source. Thesize ofnanocrystals, or the size distribution of nanocrystals, incorporated in thehost medium isselected based on the radiation spectral output required for therapeuticrequirements.The passive host medium, incorporating the said nanocrystals, is made ofadaptable,geometrically configurable, material that conforms to any desired shape.
