Preparation and optical properties of holmium oxide thin films

Optical and electrical properties of holmium thin films as a function of hydrogen concentration

“…Neither E g or α showed an appre- ciable change as a function of hydrogenation cycle. From the consistency of these parameters and the large difference between our estimated optical gap in HoH 3 phase and the holmium oxide gap: 5.2 eV [21], we conclude that the effect of oxidation is not significant in our samples.…”

Structural and optical characteristics of nano-sized structure of Zn0.5Cd0.5S thin films prepared by dip-coating method

“…The high frequency dielectric constant is connected with the contribution of the electronic polarization mechanism to the total dielectric response of Zn 0.5 Cd 0.5 S films [24]. The oscillator strength (f) is given by [19] …”

Refractive index and optical absorption properties of the complexes of a cyclobutane containing thiazolyl hydrazone ligand

“…The complex optical conductivity (r* = r 1 + ir 2 ) is related to the complex dielectric constant (e* = e 1 + ie 2 ) by [9], …”
