We study the charge dynamics and electronic structure by optical spectroscopy technique. Here we focus on the following four issues: (1) the evolution of optical spectra with Na content; (2) the spectral features specific to different regions in the phase diagram; (3) the c-axis optical response for crystal at the A-type antiferromagnetic region; (4) the optical response of misfit-layered Bi{sub 2}M{sub 2}Co{sub 2}O{sub y} (M = Ba, Sr, Ca) and Ca{sub 3}Co{sub 4}O{sub y} single crystals.
