Abstract
The nature and peculiarities of 3 p-radiative centres formation in neon crystals are studied by cathodoluminescence spectroscopy. The analysis of temperature, thickness, impurity and other effects on the intensity distribution in the “hot” luminescence spectrum proves that all the 3 p i -3 s k transition bands arise due to exciton self-trapping into the atomic-type states, and each band contains the contribution of emission from two types of centres. One type of excitation is due to self-trapping of excitons near the free surface of samples. The energy released thereat causes the ejection of excited 3 p-atoms into vacuum. The other type of centres appears during self-trapping of 3 p-excitons in bulk samples. Their formation is accompanied by the lattice rearrangement in compliance with plastic deformation type.
