On Sunday, December 22, 2024, the College of Education for Pure Sciences at the University of Mosul held a discussion for a master’s thesis that explored the linear and nonlinear optical properties of aluminum-doped tin oxide (SnO₂) prepared by the chemical spray pyrolysis method. The thesis was presented by the student Fatima Ibrahim Ismail Al-Salehi, with Professor Dr. Munir Salem Taha, the university’s assistant president for scientific affairs, attending.

The aim of the study was to analyze the effects of varying aluminum doping ratios on the optical properties of thin films. The results indicated an increase in transmittance with wavelength and a decrease in absorption, reflection coefficient, refraction, and the dielectric constant in both its real and imaginary components.

The discussion committee was chaired by Professor Dr. Mahmoud Ahmed Hamoud, with members including Assistant Professor Dr. Mervan Hafeez Younis, Assistant Professor Dr. Ivan Behnam Kroomi, and under the supervision of Instructor Dr. Ammar Tahseen Zakar along with Assistant Professor Dr. Dhufar Ali Zakar from the University of Hamdania / Laser and Photonics Center.
