In this Review, we present the recent progress of getting ordered alignment chromophores for enhanced bulk second-order optical nonlinearity, which include supramolecular interaction, light fields, electric fields and so on.
The chiral emitting ternary liquid crystals (T-N*-LCs) exhibited a photosensitive-type red CPL response controlled by an intermolecular dynamic Förster resonance energy transfer (FRET) mechanism.
Differing from the reported strategy of push or pull electron effects complexant, a new combination both and electrons complexant to enhance first hyperpolarizability is performed with two Li atom doped complexants pair difluorophenyl subunit rings. Large variance static hyperpolarizabilities (beta(0)) are exhibited at MP2/6-311++G(d,p) level. The order beta(0) values 2.9 x10(2) (complexant UD) << 5.9 x 10(3) (LL) < 1.9 10(4) (H-L) 2.3 (H(F)-L) 3.2 (L-L) 7.8 10(5) a.u. (H(F)-L(F)). It found...
The β-Ga
The electron transition between oxygen vacancies and cationic shortens the band gap of KDP crystals.
The Fe K 2+ defect introduces two states (at 2.4 eV and 6.6 eV) into the bandgap of KDP crystal as well absorption peaks at around 278 nm in xy plane.
Intentionally adding select ions such as Al3+ could be helpful in controlling the crystal habit of KDP for high yield optics. The study how affect quality can provide a basis selecting an appropriate doping level without negatively affecting optical properties crystals. Here, influence on structure and crystals have been investigated by using first-principles calculations. Theoretical calculations show that mainly replace K sites complex with intrinsic VH− point defects to form AlK2+ + 2VH−...
The behavior of the Cr 3+ centers in KDP:(CrNO 3 ) crystals is illustrated by an analysis experimental and theoretical calculations.
This work investigated the blue color center in β-Ga 2 O 3 crystals grown by EFG and obtained an effective method to eliminate it.
Herein, five lanthanide-radical cyclic dimer complexes have been obtained and complex Tb shows the relaxation behavior in zero dc field with an anisotropy barrier <italic>Δ</italic>/<italic>k</italic><sub>B</sub> = 21.6 K.
β-Ga2O3 crystal, a cutting-edge ultrawide bandgap semiconductor material, holds immense potential in ultraviolet optoelectronic, high-power, and gas-sensing devices. However, defects impurities can significantly impact the performance of β-Ga2O3-based In present study, comprehensive analysis underlying specific formation mechanism point was carried out based on density functional theory. The band structures, states, energy, optical absorption 20 types have been analyzed using HSE06 GGA-1/2+U...
The atomic configurations, energetics, electronic structures, and optical properties of [011] screw dislocation in the KDP crystal have been analyzed by using density functional theory with Perdew–Burke–Ernzerhof HSE06 functionals. results confirmed that reduces band gap introduces intermediate states into forbidden gap, which are principally derived from 2p (O)–3p (P) hybridization. Extra absorption peaks also introduced at 170, 220, 270 nm, may be attributed to dehydration process, PO2...
Abstract Defects are considered as one of the important factors affecting quality and laser‐induced damage threshold potassium dihydrogen phosphate (KH 2 PO 4 , KDP). In this study, hybrid density functional theory is used to investigate how Zn 2+ ions affect properties KDP crystal. Since crystal defects often do not exist singly but combine with each other form clusters, two charge‐compensated defect K + （Zn ion substitutes ion）+ V − （potassium vacancy）and H (hydrogen vacancy) modeled in...
Cr 3+ cluster defects induce impurity states in the crystal band gap, which may cause multiphoton absorption and optical KDP crystals under a 355 nm laser.
Surface damage products cause more UV absorption and increase surface compared to KDP crystals.
A series of 98% deuterated DKDP crystals were grown in solutions with different pD values (2.9, 3.3, 3.8, and 4.3) using the rapid growth method. Samples cut along z-direction fourth-harmonic-generation (FHG) direction which contained both pyramidal prismatic regions. The nonlinear absorption (NLA) coefficient β was obtained Z-scan method operated at FHG wavelength (266 nm) a picosecond Nd:YAG laser. According to results, 266 nm could be identified as two-photon absorption. crystal solution...
