Abstract

Disclosed is a photoreceptor fabrication method wherein a film of a solution including thermal sensitive organic selenium and tellurium compounds and a material capable of transporting at least one species of charge carrier is deposited on a sub-strate and subsequently heated until a desired amount of a selenium-tel1urium alloy is deposited within the film0 Typically, the heating is accomplished at a temperature between 100°Cand 200°C for 1 to 10 minutes0 It is important that the seleniuim-tellurium alloy include from 2 to 30 weight percent tellurium and from 98 to 70 weight percent selenium since an excessive amount of tellurium will lead to an un-desirably high, dark decay rate. Preferably the alloy includes from 20 to 25 weight percent tellurium and from 80 to 75 weight percent selenium.

Disclosed is a photoreceptor fabrication method wherein a film
of a solution including thermal sensitive organic selenium and

The organic tellurium compounds which are useful in the method
may be divalent or tetravalent forms of tellurium, The
divalent tellurium compounds are represented by the structural
formula:

R Te Te R

wherein R may be carboxymethyl, 4~acetamidopheny1, 3~hydroxy~
4~methoxyphenyl, 4-~hydroxy-~3~nitrophenyl,4=~hydroxy~3, 5~
