Abstract: | The points of lithium fluoride needles are investigated by laser photoelectronic projection microscopy. A situation in which
a single atomic-size source of electrons — an F
2 color center — is observed in the region near the point is realized. As a result of the good fluorescence properties of these
centers, these needles can be used as the active element of a scanning fluorescence microscope employing resonance transfer
of electronic excitation energy.
