| Abstract: | The optical
absorption and transmission in the pseudo-binary alloy of copper, zinc and
selenium (CuxZn1-x Se) have been investigated. The transmission
is high over most of the visible region but the absorption edge moves into the
visible spectrum as the concentration of copper in the alloy increases. The
energy gaps of the samples were found to be 1.58, 1.60 and 1.64 eV,
respectively. These values fall within the requirement for visible transmission
indicating that the films from such alloys can be used as visibly transmitting
materials for use as warm climate windows to transmit visible radiation into
buildings which have their windows coated with such films. Also, the decrease
in energy gaps of the samples with a corresponding shift in the absorption edge
towards the visible spectrum as the concentration of the copper impurity
increases, leads to an improvement in the conductivity of the alloys examined. |
