Abstract

The optical properties were studied and the values of n and k for nickel films deposited on different substrates under different environmental conditions were determined. The variation of the real and imaginary parts of the dielectric constants and optical conductivity was studied. The structures were explained in terms of interband transition at higher energies. At energies lower than 0.18 eV the relaxation mechanism and the variation of ε1 with λ2 indicated that the interband acceleration of the conduction electrons dominated over the interband transition mechanism.
