摘要： PURPOSE:To provide good performance of tight contacting with fluorescent substance and accomplish an image of high quality by using an optical interfering filter having periodical stratification of layers consisting of a low refraction factor material, with the optical film thickness specified, and layers consisting of a high refraction factor material. CONSTITUTION:The film constitution of an optical interfering filter include periodic stratification 6 of layers 3 made of a material having a low refraction factor, which is approx. 0.25 times as great as the cutoff wavelength lambda0 with the optical film thickness greater than the center wavelength lambda of the emission spectrum of the fluorescent substance, and layers 2, 4 made of a material having high refraction factor, wherein the two outside located layers shall constitute the ones with low refraction factor. Between this periodic stratification 6 and fluorescent substance layer, are interposed one over another a layer 5 consisting of or chiefly containing SiO2 in an optical film thickness from the fluorescent substance layer 0.05lambda0-0.2lambda0 or 0.47lambda0Xm+ or -0.12lambda0 (m is an integer from 1 to 10), respectively, and the mentioned layer 2 with high refraction factor in an optical film thickness of approx. 0.25lambda+0.125lambda0, and another layer 2 with high refraction factor in an optical film thickness of 0.25lambda+0.125lambda0 is provided between the periodic stratification 6 and the display window inne surface. This provides good performance of tight conatcting with the fluorescent substance, less ripples in the penetrative zone, and easy controllability for the optical film thickness of each film.

CONSTITUTION:Following constitution is adopted in a heat ray-shielding glass composed of transparent glass plate 1 alternatively covered with layers of high-refractive index material and layers of low-refractive index material. Namely, a glass plate 1 is covered with layers having optical film thickness of about 1/4 of designed wavelength lambda as first layer (2) and third layer (2) from side of the glass 1, then a layer having optical thickness of 1/8lambda is applied as fourth layer (3). The layers of odd number are the layers composed of high-refractive index material and the layers composed of low-refractive index material are layers of metal silicate having 0.005-0.040 damping factor in visible region. As the metal for forming said silicate, Ni, Al, Ta, W, Ti, Mo or Nb, etc., is preferable. As the high-refractive index material, TiO2, ZrO2, ZnO, SnO2 or In2O3, etc., is preferable.

Also, the stannic oxide films 2, 4 are formed by sputtering under a current of 2.5A by applying -400V to a metallic tin target in an argon gas including a pressure-reduced 80vol.% oxygen gas. The zirconium nitride film 3 is formed by sputtering under a current of 1.8A by applying -330V to a zirconium target in an argon gas including a pressure- reduced nitrogen gas. Thereby, a heat ray shielding board having durability can be obtained.

摘要： PURPOSE:To form compd. films stably over a long period of time by introducing a reactive gas into a treating chamber only while a base material passes the space position opposite to a cathode. CONSTITUTION:A glass substrate 19 supplied to a 1st chamber 2 of a vacuum vessel 1 is mounted on a carrier 13 and is transferred into the treating chamber of the 2nd chamber 3. An electromagnetic valve 9 of a gaseous oxygen supply pipe 11 is turned on by the control of a control circuit 30 and oxygen is supplied into the treating chamber 3. The supply of the gaseous oxygen is stopped when a 2nd limit switch 15 catches the passage of the carrier 13. Namely, the gaseous oxygen is supplied only while the glass substrate 19 passes the space position opposite to the cathode 6 and the film is formed. The glass substrate 19 subjected to the film forming treatment is taken out into the 3rd chamber 4.

摘要： PURPOSE:To obtain a heat ray shield plate having durability and low visible light transmissivity, by providing a nitride layer of a metal selected from zirconium, titanium and hafnium having a thickness of 50-600Angstrom to the single surface of a transparent substrate composed of glass or synthetic resin. CONSTITUTION:A nitride layer 12 of a metal selected from zirconium, titanium and hafnium having a thickness of 50-600Angstrom is formed to one surface of a transparent substrate 11 composed of glass or synthetic resin by a sputtering method. Whereupon, since the film 12 is composed of metal nitride, said film is not corroded in the atmosphere and has excellent abrasion resistance. By selecting the thickness of the film 12, a heat ray shield plate having solar radia tion transmissivity lower by 5% or more than visible light transmissivity within a visible light transmissivity range of 30-70% can be obtained.
