An organic-inorganic hybrid material comprising a metal oxide and a
chelating ligand is synthesized. The function of a coloring property, a
light-emitting property, or semiconductivity of the organic-inorganic
hybrid material can be controlled by chelating ligand. The
organic-inorganic hybrid material is prepared by sol-gel method using sol
which includes a metal alkoxide and/or a metal salt and a functional
chelating agent.
