  • Publication number: 20190101733
    Abstract: A low infrared absorbing lithium glass includes FeO in the range of 0.0005-0.015 wt %, more preferably 0.001-0.010 wt %, and a redox ratio in the range of 0.005-0.15, more preferably in the range of 0.005-010. The glass can be chemically tempered and used to provide a ballistic viewing cover for night vision goggles or scope. A method is provided to change a glass making process from making a high infrared absorbing lithium glass having FeO in the range of 0.02 to 0.04 wt % and a redox ratio in the range of 0.2 to 0.4 to the low infrared absorbing lithium glass by adding additional oxidizers to the batch materials. A second method is provided to change a glass making process from making a low infrared absorbing lithium glass to the high infrared absorbing lithium glass by adding additional reducers to the batch material. In one embodiment of the invention the oxidizer is CeO2. An embodiment of the invention covers a glass made according to the method.

  • Patent number: 10096799
    Abstract: An organic light emitting diode includes a substrate having a surface modification layer. The surface modification layer includes a first film and a second film. The first film has a coefficient of expansion that is greater than the coefficient of expansion for the second film. The second film has ridges and troughs. A method of making a surface modification layer. A first film is formed over a substrate. The coated substrate is heated to expand the first film to a second surface area. A second film is formed over the expanded first film. The substrate coated with the first and second films is cooled to form ridges and troughs in the second film.
