Abstract
The photoluminescence and possible cathodoluminescence of cosmic dust is considered. It is shown that the dust of planetary nebulae can luminesce under the action of fluxes of charged particles. The results of a comparative analysis of unidentified emission features in the optical spectrum of the nebula NGC 7027 and the luminescence emission of a number of minerals is presented. It is shown that the dust in this nebula includes diamond grains.
