Description
Molybdenum trioxide (MoO3) patterned at the nanometer scale is combined with the same material in its bulk form to produce Bragg mirrors with enhanced photoactive properties. MoO3 undergoes coloration with exposure to UV light but a multilayer structure which alternates between nanostructured and bulk MoO3 is 2.5 times more effective. Measurements with various multilayer arrangements suggest the proximity of bulk and nanostructured MoO3 favors the photoreaction with structural water. A possible minor contribution from electronic band shifting is also discussed.
