| Popis: | Different types of luminescence (photoluminescence, cathodoluminescence, X-ray luminescence in the range from 360 to 900 nm of monocrystalline diamond powders with grains from 125/100 to 250/200 |j,m) were studied. The powders were divided into different groups according to the perfection degree of their crystal structure and magnetic susceptibility value. At the room temperature the H3 luminescence of a diamond defect prevailed in all groups of crystals. At the liquid nitrogen temperature in the spectra of cathodoluminescence nickel centers dominated. Using selected diamonds and Sylgard 184 polysiloxane elastomer the samples of composite scintillators were made and their radiation resistance investigated. The higher radiation resistance relative of the standard YSO:Ce scintillators to the irradiation with fast electrons was installed. |
