Webb1 sep. 2016 · Photoluminescence occurs in many bulk materials that are direct band gap semiconductors and also because of impurities that absorb and emit light in an otherwise transparent medium. We discuss examples of both situations in this installment. Chromium Impurities in Aluminum Oxide Webb1 juni 2024 · Ruby, Cr +3 -doped aluminium oxide (Cr:Al 2 O 3 ), is one of the most renowned laser materials. In the 1960s, ruby single crystal was used as the gain medium in the first-ever demonstration of solid-state stimulated laser emission [6]. This breakthrough paved the way for many new scientific and technological opportunities. grub spot hounslow
