2. 1. Electrochromism in Metal Oxide Thin Films : Towards long-term durability and materials rejuvenation

   Author : Rui-Tao Wen; Claes-Göran Granqvist; Agustín R. González-Elipe; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochromic; smart windows; long-term durability; degradation kinetics; ion trapping; de-trapping; materials rejuvenation; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Abstract : Electrochromic thin films can effectively regulate the visible and infrared light passing through a window, demonstrating great potential to save energy and offer a comfortable indoor environment in buildings. However, long-term durability is a big issue and the physics behind this is far from clear. READ MORE

4. 2. Electrochromic Nickel – Tungsten Oxides : Optical, Electrochemical and Structural Characterization of Sputter-deposited Thin Films in the Whole Composition Range

   Author : Sara Green; Gunnar Niklasson; Claes-Göran Granqvist; Esteban Avendaño; Aline Rougier; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrochromism; Nickel oxide; Tungsten oxide; Lithium intercalation; Sputtering; Thin films; Nanostructures; Optical properties; Solid State Physics; Fasta tillståndets fysik;

   Abstract : This thesis investigates the electrochromic NixW1-x oxide thin film system, where 0 < x < 1. The thin films were deposited by reactive DC magnetron co-sputtering from one Ni and one W metal target. In addition, Ni oxide was deposited with water vapor added to the sputtering gas. READ MORE

5. 3. Components of smart windows : Investigations of electrochromic films, transparent counter electrodes and sputtering techniques

   Author : Lisen Kullman; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : In smart windows, the transmittance of visible and near infrared radiation can be reversibly and persistently modulatcd by an applied voltage pulse (~2 V). The micrometer-thick multi-layer structure contains two electrodes capable of charge insertion. One of these electrodes must be electrochromic; usually it consists of tungsten oxide. READ MORE

6. 4. Electrochromic nanostructures based on tungsten trioxide for reflective displays

   Author : Marika Gugole; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; electrochromism; structural colors; reflective displays; WO3;

   Abstract : Our lives are dominated by the usage of displays. Every day we spend hours looking at displays and our eyes are surely affected by them. Reflective displays have gained a lot of attention in recent years due to their lower impact on our eyes' health, very low power consumption, and high performance in sunlight. READ MORE

7. 5. Electrochromic Plasmonic Metasurfaces for Reflective Displays

   Author : Kunli Xiong; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plasmonic; Keywords: Colorful electronic paper; Conductive polymer.;

   Abstract : Plasmonic nanomaterials provide brilliant colors that arise from the ambient light coupling to the free electrons in metals. In the Roman empire, noble metal nanoparticles were used for staining glass in Church windows and tableware. READ MORE
