Abstract

Transparent ZnS: Mn thin films were produced by chemical bath deposition (CBD) technique at 80 degrees C for 4h, 6h and 8h durations. The optical properties such as optical transmittance (T %), reflectance (R %), extinction coefficient (k) and refractive index (n) were deeply investigated in terms of contribution ratio, wavelength and film thickness. The optical properties of ZnS: Mn thin films were determined by UV/vis spectrophotometer transmittance measurements in the range of lambda= 300-1100 nm. Optical transmittances of the films were found from 12% to 92% in the visible region. The refractive index (n) values for visible region were calculated as 1.34-5.09. However, film thicknesses were calculated between 50 and 901 nm by gravimetric analysis.
