Cathodoluminescence of regolith returned by the Luna 16 probe
Abstract
Local variations in intensity and spectral composition of the cathodoluminescence of lunar regolith are studied. The variations are caused by the nature, structural characteristics, and amount of the regolith as well as by impurities. It is shown that cathodoluminescent emission is also associated with changes in lunar surface temperature. Periodic illumination of the lunar surface leads to the appearance of a temperature gradient that is normal to the lines of longitude. The observations were made with a scanning electron microscope equipped with an attachment for the temperature variations.
