Quantum degenerate gases of ytterbium atoms in three-dimensional optical lattices are studied for bosonic isotopes and mixtures of bosonic and fermionic isotopes. A quantum phase transition from a superfluid to a Mott insulating state is observed for bosonic isotopes. In the deep Mott insulating region, we perform one-color photoassociation spectroscopy and investigate the site occupancy. In addition, Bose-Fermi mixtures of Yb isotopes in optical lattices are studied using two different combinations of mixtures.
