Role of oxadiazole moiety in different D–A polyazothines and related resistive switching properties

Facile Synthesis of AgCl/BiYO3 Composite for Efficient Photodegradation of RO16 under UV and Visible Light Irradiation

“…Hence, the onset absorption of AgCl/BiYO 3 composite was blue shifted with the increasing of AgCl contents. The optical bandgap energy (E g ) can be determined by using the Kubelka-Munk relation as shown in (1) (Pan et al 2013;Yan et al 2013);…”

Hybrid nickel-free graphene/porphyrin rings for photodegradation of emerging pollutants in water

“…S6 †) we measured the optical bandgap (E g ) as E g ¼ 2.2 eV and thus we estimated the HOMO energy level as E HOMO ¼ E LUMO À E g , nding the eqn (1) E HOMO ¼ À6.4 AE 0.2 eV. [49][50][51] To our knowledge, this is the rst time that HOMO and LUMO energy levels of cyclic porphyrins-based copolyformal are measured by CV.…”

Highly fluorescent semiconducting pyrazoline materials for optoelectronics

“…HOMO, LUMO and bandgap energies (E g ) were calculated using formal empirical formula (HOMO = À([EA onset ] ox + 4.8) eV, LUMO = À([EA onset ] red + 4.8) eV and E g = LUMO-HOMO) [41,42]. The oxidation onsets of I, II and III were estimated to be 0.65, 0.83 and 0.56 V, which correspond to HOMO energy levels of À5.45, À5.63 and À5.36 eV, respectively [41][42][43][44][45]. The reduction potential onsets of I, II and III are À0.51, À0.63 and À0.62 V, corresponds to LUMO energy levels of À4.29, À4.17 and À4.18 eV, respectively, the energy gap (E g ) of materials I, II and III were found to be 1.2, 1.46 and 1.18 eV.…”
