Abstract

Excimer laser dyes are used for charge generation in the photoconductors of photocopies. They may make excellent charge generation compounds because: (a) they absorb in the appropriate spectral range, from UV to near IR (Z800nm); (b) they have the appropriate energy level for charge injection; (3) they are photochemically very stable (as required for excimer pumping); and (d) they exhibit some solubility in standard and innocuous solvents such as methanol or ethanol and, moreover, fine dispersive solutions are possible.
