Synchrotron-Excited Luminescence of Natural Zircon
The luminescence properties of two single zircon crystals from kimberlite of Yakutia have been studied, excited by the DORIS HASYLAB synchrotron, Germany, within energy range from the visible to the soft X-ray region (5-25, 50-200, and 500-620 eV) at temperatures of 300 and 10 K. The luminescence sp...
