Relationship between the photocatalytic and photoluminescence properties of zinc oxide doped with copper and manganese

Comparison of the photocatalytic and photoluminescence properties of zinc oxide lightly doped with copper and manganese shows that the relationship between these two processes is due to several reasons, the most important of which are the crystalline state of the material and the type and concentration of the modifier. Raising the concentration of dopants makes the photoluminescence intensity higher and reduces the photocatalytic activity. It is shown that the mechanism by which a dopant is incorporated also affects the relationship under consideration and leads in some cases to deviation from the tendency mentioned above.
