A spectral power distribution (SPD) fusion lighting apparatus includes a first visible light source with a first SPD, a second visible light source with a second SPD, a driver circuit, and a controller. The first SPD is different than the second SPD markedly in a 50 nm wavelength range. The controller toggles the turning on of the first visible light and the second visible light at a frequency greater than 25 Hz. The first visible light source is turned on during one half of the duty cycle, whereas the second visible light source is turned on during the other half of the duty cycle. The first visible light source and the second visible light emit similar light outputs and have similar chromaticity coordinates on the CIE 1931 color space chromaticity diagram. In some embodiments a sound wave generator is used to generate a sound wave at the same frequency.

A self-disinfecting photocatalyst sheet includes a substrate material and a photocatalyst layer with a primary photocatalyst and a secondary photocatalyst. The primary photocatalyst is a metal oxide photocatalyst, whereas the secondary photocatalyst is a metallic photocatalyst. The substrate material binds the photocatalyst layer by either connecting a metal ion of the primary photocatalyst and/or the secondary photocatalyst through two oxygen atoms of a carboxyl group (COO), or by forming hydrogen bonds between a carbonyl group and a surface hydroxyl group (OH) of the primary photocatalyst. The self-disinfecting photocatalyst sheet is activatable by a visible light and can self-disinfect against bacteria and viruses.
