Optical microcavities based on lithium fluoride films treated by low-energy electrons to create visible-emitting F-2 color centers have been fabricated, and their radiative properties characterized for the first time. By tuning the photon cavity mode to the maximum of the luminescence band for the F-2 centers (similar to 670 nm), spectral narrowing, peak-intensity enhancement of the emission band as well as a highly directional radiation pattern have been observed comparatively for experiments performed on a half-cavity and a full microcavity, Spontaneous emission decay times have been measured, and a shortening of lifetime by the cavity has been observed.

Abstract
Optical microcavities based on lithium fluoride films treated by low-energy electrons to create visible-emitting F-2 color centers have been fabricated, and their radiative properties characterized for the first time. By tuning the photon cavity mode to the maximum of the luminescence band for the F-2 centers (similar to 670 nm), spectral narrowing, peak-intensity enhancement of the emission band as well as a highly directional radiation pattern have been observed comparatively for experiments performed on a half-cavity and a full microcavity, Spontaneous emission decay times have been measured, and a shortening of lifetime by the cavity has been observed.
