    • Low-E glass coated glass articles are comprised of a glass substrate and a multiple layer coating on a surface of the glass substrate. Relatively high light transmissivity of greater than about 72% and satisfactory color characteristics are achieved. The coating includes a layer of a transparent dielectric material adjacent the surface of the glass substrate, and respective layers of nitrided nichrome and silver each of which are formed by sputter-coating onto the glass substrate in a nitrogen-containing atmosphere. Most preferably, the coating also includes a layer of silicon oxynitride interposed between the layer of dielectric material and the layer of nitrided nichrome. The silicon oxynitride layer may include an oxygen gradient layer wherein the concentration of oxygen decreases from one location in the silicon oxynitride layer to another location at a different depth in that same layer. If present, the oxygen gradient is most preferably such that the greater amount of oxygen concentration is nearer the bottom of the layer (i.e., towards the glass substrate) with the lesser amount of oxygen concentration being nearer the top of the layer (i.e., away from the glass layer).
    • Low-E玻璃涂层玻璃制品由玻璃基板和玻璃基板表面上的多层涂层构成。 实现了大于约72%的高透光率和令人满意的颜色特性。 该涂层包括邻近玻璃基板表面的透明电介质材料层,以及各自的氮化镍铬合金层和银层,其各自通过在含氮气氛中溅射涂覆在玻璃基板上形成。 最优选地,涂层还包括置于介电材料层和氮化镍铬合金层之间的氮氧化硅层。 氧氮化硅层可以包括氧气梯度层,其中氧浓度从氧氮化硅层中的一个位置降低到同一层中不同深度的另一个位置。 如果存在氧气梯度,则最优选地,氧浓度越大,层的底部越接近玻璃基底(即朝向玻璃基底),氧浓度越接近层的顶部(即,离开 从玻璃层)。

    • An infrared reflecting interference filter capable of transmitting a desired proportion of visible radiation while reflecting a large portion of incident solar radiation is provided. The filter comprises a transparent substrate onto which is deposited a dielectric layer, followed by metal and dielectric layers. In between each of the dielectric and metal layers is deposited a precoat layer that promotes adhesion between the dielectric and the metal. One aspect of the invention is the use of a film comprising nickel and chromium nitride for each of the metal precoat layers. These precoat layers are thin so that there is less absorption of visible light but yet maintains good adhesive properties. Another aspect of the invention is the use of silver as the metal layer. Specifically, silver is sputtered in an atmosphere containing a mixture of nitrogen and argon or other inert gas. It was found that the presence of nitrogen produces a silver layer that is more durable than silver films sputtered in an atmosphere containing essentially pure inert gas. In one embodiment, the interference filter comprises a glass substrate onto which is deposited a thin-film design consisting of five layers, namely: titanium dioxide, nickel-chromium nitride, silver, nickel-chromium nitride, and silicon nitride.
    • 提供能够在反射大部分入射的太阳辐射的同时传输期望比例的可见光的红外反射干涉滤光器。 滤光器包括透明基板,在其上沉积介电层,其次是金属和电介质层。 在每个介电层和金属层之间沉积预涂层,其促进电介质和金属之间的粘附。 本发明的一个方面是使用包含镍和氮化铬的膜用于每个金属预涂层。 这些预涂层是薄的,因此对可见光的吸收较少但仍具有良好的粘合性能。 本发明的另一方面是使用银作为金属层。 具体地说,将银溅射在含有氮气和氩气或其它惰性气体的混合物的气氛中。 发现氮的存在产生比在基本上纯的惰性气体的气氛中溅射的银膜更耐用的银层。 在一个实施例中,干涉滤光器包括玻璃基板,在其上沉积由五层组成的薄膜设计,即:二氧化钛,镍 - 氮化铬,银,镍 - 氮化铬和氮化硅。
