Fotomeetriteks

Fotomeetriteks refers to a category of materials that exhibit a change in their physical properties when exposed to light. This phenomenon is central to the functioning of various optical and electronic devices. The term itself is a portmanteau, combining "photo" (light), "meetri" (measurement or change), and "tekst" (material or fabric). Essentially, it describes light-responsive materials where exposure to photons triggers a measurable alteration.

These alterations can manifest in numerous ways. For instance, some fotomeetriteks materials change their electrical conductivity upon illumination, a principle utilized in photodetectors and solar cells. Others might undergo a change in their optical properties, such as transparency, color, or refractive index. Photochromic materials, which reversibly change color when exposed to UV or visible light, are a common example of this class.

The applications of fotomeetriteks are diverse and continuously expanding. They are integral to digital cameras, where light sensors convert photons into electrical signals. In the field of optics, they are used in smart windows that can adjust their tint based on sunlight intensity, as well as in optical data storage and display technologies. Research is ongoing to develop new fotomeetriteks with enhanced sensitivity, faster response times, and greater durability for future technological advancements.
