摘要： A transparent ceramic substrate is covered by a photocatalyst layer, at least partially. The photocatalyst layer includes a semiconductor material that, upon exposure to electromagnetic radiation, forms a plurality of electrons and a plurality of holes that remain confined to the photocatalyst layer. The transparent ceramic substrate has a diameter that is larger than the wavelength of the electromagnetic radiation for light trapping.
