What is the principle of diffuse reflectance spectroscopy

also revealed that the films show very high absorbance in the UV-VIS regions of the applications. The band gap of the thin films is in the range of 1.50 – 1.75eV. The values showing considerably variation with annealing temperatures. The wide range of band gap expands the possibilities of using the thin films for solar photo voltaic application.

The band gap refers to the energy difference between the top of the valence band filled with electrons and the bottom of the conduction band devoid of electrons. The wavelength range of the UV-3600 Plus is extremely effective for band gap calculations.

Direct and indirect band gaps Wikipedia

In semiconductor physics, the band gap of a semiconductor is of two types, a direct band gap and an indirect band gap. The minimal-energy state in the conduction band and the maximal-energy state in the valence band are each characterized by a certain crystal momentum (k-vector) in the Brillouin zone.
