Low-energy electron irradiation of LiF polycrystalline films induces the efficient formation of color centers laser active in the green-red spectral interval. The sizeable gain coefficient together with the consistent increase of the real part of the refractive index, combined with the use of electron-lithography techniques, look promising for the realization of optically active optoelectronic components. Photoluminescence represents a simple and powerful tool for their development, specially on samples characterized by restricted geometries and/or non-transparent substrates.
