Background

Ultraviolet sterilization is the purpose of sterilizing bacteria by irradiating ultraviolet rays to destroy and change the DNA (deoxyribonucleic acid) structure of microorganisms so that the bacteria die immediately or cannot reproduce offspring. The true bactericidal action is UVC ultraviolet ray, because the C-band ultraviolet ray is easily absorbed by the DNA of the organism, and the best ultraviolet ray is about 253.7 nm.

The ultraviolet ray sterilization lamp mainly has two types of emission spectral lines of 254nm and 185nm, the 254nm ultraviolet ray can kill bacteria by irradiating DNA of microorganisms, the 185nm ultraviolet ray can change O2 in the air into O3 (ozone), the ozone has strong oxidation effect and can effectively kill the bacteria, and the dispersivity of the ozone can just make up for the defect that the ultraviolet ray only propagates along a straight line and has dead angles in disinfection.

When a sufficient amount of titanium (Ti) is added to silica glass during refining, the ultraviolet rays transmitted through the silica glass are cut off at 200nm or less, and the transmission of the ultraviolet rays at 254nm is not substantially affected.
