Abstract

Laser radiation has been used to excite fluorescences spectra of Fe and Co atoms isolated in solid inert gas matrices. For each atom, about 50 fluorescence lines have been observed in the $11000-25000 cm^{-1}$ region. The fluorescence transitions terminate in either the $a^{5}D$ or the $a^{5}F$ quintet levels in the case of Fe and for Co in either the $a^{4}F$ or $a^{2}F$ levels. Matrix shifts, matrix concentration effects and the laser intensity dependence of fluorescence lines on both the low and high frequency sides of the excitation will be discussed.
