Optical Properties of Some Dielectric/Copper Alloy Film Systems

Yu Shanqing Zhang Xiaoping Ma Minwei (Shanghai Institute of Energy,Shanghai Academy of Science)  
The spectral transmittance(T_λ) and spectral absorbance(A_λ) of D/CA systems,which consist of a dielectric overcoating D(D=SiO,SnO_2 ZnS or CdS)and a co-pper alloy layer′CA,were studied in the wavelength range of 320-1000nm.Theinfluence of D overcoating and CA layer on the properties of spectral selectivity ofT_λ and A_λ of optical systems was dsicussed.It is shown that in the case of a sin-gle layer of CA coating,the spectral selectivity of either T_λ of A_λ in the thickne-ss range of 5.1—30nm of CA films is not found to be clearly changed.The T_λis monotonically decreased and A_λ increased with increase in the thickness of CAlayers.In the case of D/CA unsymmitrical optical systems,the properties and thi-ckness of D overcoating deposited on CA basic layer directly influence on wavepatterns(i.e.spectral selectivity)of A_λ.With the D/CA optical systems consistingof a D overcoating with different thickness and a CA baic layser with same thick-ness,identical wave patterns of A_λ can be obtained.The thickness of CA layers pla-ys an important role for the light absorption of D/CA optical systems.When CAlayer becomes thicker,its spectral absorbance will increase.
