It is proved that the pulsed cathodoluminescence of solids, which occurs when they are irradiated by electron beams of nanosecond duration with a peak power density of 1-10 MW/cm2, is promising for a versatile non-destructive analysis of the substance.
The desktop version of pulse cathodoluminescence spectrograph the CLAVI is created.
The luminescent method of detection of the second crystalline phases of low content in single crystals and ceramics of yttrium-aluminum garnet and yttrium oxide activated by neodymium is developed and used.
Different charged ions (Zr4+ and Zr3+, Hf4+ and Hf3+) of sintering additives affecting the efficiency of laser generation at optical transitions of rare-earth ions were found in the crystal matrices of ceramics based on yttrium aluminum garnet and yttrium oxide.
The bases of luminescent method of Express determination of the region (country) of the Deposit of precious stones are developed.
