General description
Camphorquinone (CQ) absorbs UV radiation in the region of 200-300nm due to the Π−Π* transition and visible light (400-500nm) due to the n, Π* transition of the α-dicarbonyl chromophore.
Application
CQ-amines are used as a photo initiators for free radical polymerization. CQ was used as an initiator in the preparation of silver nanoparticle/silica/ polymer nanocomposites. Photopolymerization kinetics of dimethacrylates were studied using the CQ/amine initiator system.

The primary absorber in dental resins is the photoinitiator, which starts the photo polymerization process. We studied the quantum yield of conversion of camphorquinone (CQ), a blue light photoinitiator, in dental resin composites using a LED lamp (3M FreeLight) and
