1. Reflective structural colors and their actuation using electroactive conducting polymers
Sammanfattning : The integration of inorganic photonic nanostructures with organic materials opens new possibilities to dynamically modify the optical response of photonic devices. This thesis focuses on how to generate efficient reflective structural colors and tune them in combination with a conducting polymer (CP). LÄS MER
2. Seeing the invisible: Evolution of wing interference patterns in Hymenoptera, and their application in taxonomy
Sammanfattning : The remarkably thin transparent wing membranes in tiny wasps may appear to have a simple structural design, but hide a largely unexplored complex of micro-morphological features that serve aerodynamics and may also function in visual signaling. I found that when such small transparent wings are viewed against a dark background they display vivid structural color patterns due to thin film interference, and named them Wing Interference Patterns (WIPs).

3. Electrochromic nanostructures based on tungsten trioxide for reflective displays
Sammanfattning : 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. LÄS MER
4. WO3 for reflective displays in color
Sammanfattning : Reflective displays, also known as electronic paper, are very attractive due to their low power consumption and great visibility under bright ambient light conditions. However, reflective displays in color are still limited on the market for two main reasons. LÄS MER
5. The Visible and the Invisible : Color Contrast Phenomena in Space
Sammanfattning : This study deals with the changes in color that arise in space, primarily simultaneous contrast in three dimensions. The typical account of simultaneous contrast is that the contrast phenomenon occurs between two or more color surfaces seen together, thus affecting one another. LÄS MER
