Abstract

Optical microcavities based on lithium fluoride films treated by low-energy electrons to create visible-emitting F2color 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 F2centers (approximately 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.
