NLO definition
Examples of NLO in a sentence
Such a broad emission band is apparently an NLO process, considering its up-conversion characteristic from the NIR light to the visible range.
The non-centrosymmetric nature of the TPE crystal endows its potential NLO properties.
The NLO response of the prototype AIEgen tetraphenylethylene (TPE) demonstrates various NLO properties, including SHG, TPF and 3PL depending on the wavelength of the excitation beam.
Theoretical calcula- tions together with polarization-dependent experiments show that the transition dipole moment is one of the key parameter for the design of NLO AIEgen materials with large hyperpolarizabilities.
Indeed, the NLO spectra of TPE crystals exhibit strong SHG and multiple photon excitation fluorescence (Fig.
The two-photon nature of the two NLO process is further demonstrated by the slope fitting of the relation between the NLO intensity and the pump laser power, which indicates a quadratic dependence (Fig.
NLO examinations were performed using a home- built set-up.37 The calculations were conducted in Gaussian09 (Revision D.01) with ▇▇▇▇▇▇–▇▇▇▇▇–Ernzerhof (PBE) density function.55 The basis sets were employed lanl2dz with pseudo potentials for Br and I, and 6-31G(d) for other elements.
We believe that the discovery of nonlinear optical (NLO) properties of these classic AIEgens may open a broad research area to explore new organic NLO materials and applications.
Importantly, the NLO signals of TPE show distinct wavelength dependent features.
We believe this work may open a new area for the exploration of NLO materials based on AIEgens.
