First-principles study of electronic properties of Zn and La doped and co-doped anatase TiO2 by Vivek Christhunathan, Pau Farràs, Mingming Tong

“…Properties of the chemically modified TiO2 were computationally predicted in terms of lattice parameters, electronic band structure, density of states, charge density, and absorption spectrum. It was found that co-doping TiO2 using Zn2+ and La3+ significantly reduced the bandgap and improved relative stability, and enhanced photocatalytic activity in the visible-light region was observed in comparison with pure TiO2. …”

Design and Tuning of Photoswitches for Solar Energy Storage by Raul Losantos, Diego Sampedro

“…Starting from basic structures, we use density functional theory (DFT) computational modelling to propose two different strategies to increase the energy difference between isomers and to tune the absorption spectrum. The inclusion of a mechanical lock in the structure, via an alkyl chain and the presence of a hydrogen bonding are shown to directly influence the energy difference and the absorption spectra. …”

Experimental Detection and Simulation of Terahertz Spectra of Aqueous L-Arginine by Lei Hou, Junnan Wang, Haiqing Wang, Lei Yang, Wei Shi

“…In this paper, a method for direct detection of THz absorption spectra of L-arginine suspension was proposed by using a strong field THz radiation source combined with a polyethylene cell with micrometer thickness in a THz time-domain spectroscopy system. And the THz absorption spectrum of L-arginine solution was simulated by the density functional theory and the simulation result is in good agreement with the experimental results. …”

Effect of graphene oxide on spectral-luminescenct properties of xanthene dye by E.V. Seliverstova, E.Zh. Alikhaidarova, N.Kh. Ibrayev

“…During the interaction of graphene oxide (GO) with a cationic dye, aggregation of Rhodamine 6G occurs, which is expressed as an increase in the optical density of the short-wavelength shoulder in the absorption spectrum of the dye. GO sheets can act as adsorption centers for dye molecules due to the influence of the Coulomb and intermolecular forces between GO and Rhodamine 6G. …”
