AI Technical Summary
Technical Problem
The existing GaN-based near-UV LED light source is complex in the manufacturing process, and the phosphor used cannot fully exert the sensitization effect when used as a photosensitizer.
Method used
Specific fluoroolefin compounds with an aromatic cyclic hydroxymethane (arylcarbazole) framework are used as photosensitizers, and the sensitization effect of the photosensitive material is improved by combining it with the photosensitive material.
Benefits of technology
The efficient sensitization of photosensitive materials is achieved, the efficiency of photosensitization reaction is improved, and the manufacturing process of light sources is simplified.
