## Abstract We studied the dielectric functions of Ge nanocrystals obtained by crystallization of amorphous Ge thin films embedded in SiO~2~. Partial crystallization of films was induced by thermal annealing. Crystalline regions gave rise to clear spectral features due to interband transitions whos
