Advances in sensor technologies and the more widespread deployment of sensors are continually improving safety, quality of life and industrial productivity. Many of the most reliable chemical, biological and gas sensors are in some way based on light, with current technology exploiting wavelengths from deep ultraviolet to far infrared. Within this field, ultraviolet light with wavelengths between 210 and 230 nm in the ultraviolet C (UVC) spectral range has a vital role because of the strong and specific interaction between these wavelengths and many analytes, especially those measured during...Read full article
