Abstract:
Solution growth technique was used to deposit thin films of
Manganese Suphide (MnS), Calcium Sulphide (CaS), Magnesium
Sulphide (MgS), Barium Sulphide (Bas), Zinc Fluoride (ZnFz) and
Calcium Oxide (CaO) on micro-slides (Substrates) at different bath
parameters which include temperature, molarity of solution,
Volume of solution and water, time of d.eposition and pH.
The absorbance, A was measured using spectrophotometer
ranging from ultraviolet to visible regions. The Transmittance, TI
Reflectance, R Energy band gap, E, Absorption coefficient, a,
Extinction coefficient, K, Refractive index, n, Dielectric constant, 6,
Optical conductivity, oop1 and Thickness t, were calculated. The
percentage transmittance of the films were measured at infrared
region using infrared spectrophotometer. Graphs of there
properties were plotted against wavelength and photon energy to
determine the behaviour of each film at ultraviolet, visible and
Infrared regions of the electromagnetic spectrum. The topographic
structure of the films were studied using photomicrography
.method or optical microscope. Energy Dispersive X-
