“…Also, the knowledge of the index n 0 indicates the compactness of our sample and aids in gaining insight into its good quality. 45 In this paper, the refractive index of ferrite is determined according to Moss's empirical relation as reported:…”

Experimental and modeling study of ZnO:Ni nanoparticles for near-infrared light emitting diodes

“…The optical band gap E g of Zn 0.95 Ni 0.05 O semiconductor was calculated using the Tauc's law given by: 39–41 αhν = A ( hν − E g ) n where hν is the energy of the incident photon, α is the absorption co-efficient and A is a constant. The type of transition depends on the exponent n which can take two values depending on whether the transition is allowed direct ( n = 1/2) or indirect band gaps ( n = 2).…”

A structural study of PrCrO 3 under extreme conditions: a comparison with the effects of doping

“…The semiconducting orthorhombic PrCrO3 (with Cr in the +3 oxidation state) has been shown by optical methods to have an estimated band gap in the range of 3.20–3.26 eV and as a result is a good candidate for opto-electronic devices [5]. Magnetically, the material is antiferomagnetic with a Néel temperature of 237 K. At 4.2 K, the normalCr3+ spin structure is G-type with an additional weak ferromagnetic component laying along the c-axis [6].…”
