LIGHT TRANSMISSIVE MATERIAL AND LAMP, AND GAS TREATING DEVICE AND GAS TREATING METHOD

摘要

There is provided a light transmissive material capable of reducing the attachment of contaminants to its front surface, and easily removing contaminants even when the contaminants have been attached thereto. There are also provided a lamp including a light emitting tube formed of the light transmissive material as well as a gas treatment device and a gas treatment method utilizing the light transmissive material.;The light transmissive material according to the present invention includes a glass substrate having a front surface on which a surface layer formed of nano-silica particles is provided. The lamp according to the present invention includes a light emitting tube formed of the above-described light transmissive material, in which the surface layer is provided on an outer surface of the light emitting tube. The gas treatment device according to the present invention includes: a chamber having a treatment space through which a gas to be treated flows; and an ultraviolet lamp disposed so that at least a part of a light emitting tube is exposed to the treatment space. The light emitting tube in the ultraviolet lamp has an outer surface on which a surface layer formed of nano-silica particles is provided.
