Abstract
Thin films of Strontium iodide (SrI2) were successfully deposited on glass slides at a temperature of 50°C in a chemical bath for 7½ hours, using improved solution growth technique (SGT) in different molar concentrations ranging from 0.03M. 0.06M, 0.09M, 0.12M and 0.15M. A Double beam spectrophotometer was used to obtain the spectra absorbance data while the other properties were calculated using the theory. The average optical and solid state properties include Absorbance (A)=0.149-0.541 Reflectance (R)- 0.141-0.203, Transmittance (T)=0.288-0.710, Absorbing Power (a)=0.342- 1.25, Refractive Index (n)=2.20-2.64. Film Thickness (0=0.937-0.972, and Band Gap (Eg)-3.318-3.419. While the Strontium thin films can be used as antireflection coatings, it is observed that thin films with refractive index greater than 1.9 can be used as Construction of Poultry house, solar cells, etc. The deposited thin films have band gap within light energy range from 1.5-3.0 eV of the electromagnetic spectrum and could be useful for applications in solar electricity for rural electrification which improves the standard of living. telecommunication
