Abstract
PURPOSE:To improve reliability in a lamp for hours as well as to make the light intensity of a wavelength of 185nm in particular so as not to be lowered even by a secular change by applying coating treatment to the inner wall of a ultraviolet luminous bulb. CONSTITUTION:Silane gas and oxide gas are made to flow to the inner side of a luminous lamp tube 1 at the specified flow ratio, irradiating an ultraviolet illuminant containing a wavelength of 185nm from the outside of the lamp tube 1, whereby a photochemical reaction is caused and an inner surface of the lamp tube 1 is coated with SiO2 thin film. At this time, simultaneously this lamp tube is heated, and when temperature is set to 250 deg.C-450 deg.C or so and the SiO2 thin film 4 is formed there, this SiO2 film is able to form a yet finer hard film. With this formation, a recess 2 so far formed in the inner surface of the lamp tube 1 is filled up by the SiO2 film 4, so that it will come to such a state that mercury cannot be stuck to the recess 2.
