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.

Excimer Laser Dyes for Charge Generation

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.

The following compounds were used as charge generation compounds: HEXACYANINE-3, DOTCI and STYRYL-9. The peak in the fluorescence of a dye when pumped by an excimer laser indicates the longest useful wavelength of that dye as a charge generation compound.
