Silicon-Based Visible-Blind Ultraviolet Detection and Imaging Using Down-Shifting Luminophores




A visible-blind UV detector design combining conventional silicon photodiodes with down-shifting luminophores in a light trapping configuration enables a response in a selective spectral band between 300 nm and 360 nm. An array of such detectors demonstrates the potential for using these structures in UV imagers, and suggests compatibility with large-area, CMOS-compatible Si electronics and photonics.
