A composition for use in constructing a photosensitive film (10) for recording an image. The composition comprises first, second, and third particles (12-14). Each particle type comprises a crystalline base material having a trap dopant and a color dopant deposited therein. Each color dopant has a different spectral sensitivity. In one embodiment, each of the trap dopants has a different activation energy for releasing electrons traps therein into the conduction band of the crystalline base material. In another embodiment, the base material is applied as a thin film and the dopant atoms (101-103) deposited therein in a pattern provide the equivalent of the three particle types (100-112).
