Figure 2

Changing the optical properties of semi-transparent silver by sputtered TiO2 coatings.

(a) Experimental and (b) calculated normal-incidence transmittance spectra for 23-nm-thick silver layers that are either uncoated or coated with a TiO2 layer ranging in thickness from 18 nm to 57 nm. The experimental spectra are obtained from the average of 5 independent measurements, where each measurement is made from an average of 40 traces. Photographs of the samples placed on the printed UBC logo are shown at the top of panel (a) to highlight the visible appearance changes caused by the thin TiO2 layer. The leftmost photograph is of uncoated silver and the adjacent images are of coated silver (in order of increasing coating layer thickness from left to right).
