Trion oscillator strength

Solid State Communications, 2003
Our new commutation technique for excitons interacting with electrons allowed us to derive the X− trion expansion in terms of exciton–electron pairs while taking exactly into account the fact that the exciton can be made with any of the two electrons.

Reducing the Optical Gain Threshold in Two-Dimensional CdSe Nanoplatelets by the Giant Oscillator Strength Transition Effect.

Journal of Physical Chemistry Letters, 2019
Two-dimensional CdSe nanoplatelets are promising lasing materials. Their large lateral areas reduce the optical gain threshold by increasing the oscillator strength and multiexciton lifetimes but also increase the gain threshold by requiring multiple ...

Exciton states and oscillator strength in few-layer α-tellurene

Applied Physics Letters, 2019
Tellurene is an elementary two-dimensional (2D) semiconductor material that has attracted intensive attention. Here, first-principles methods are used to explore the effects of excitons on the optical properties of few-layer α-tellurene by considering ...

Ni I oscillator strengths

Journal of Quantitative Spectroscopy and Radiative Transfer, 1985
Abstract Oscillator strengths of 150 Ni I lines in the spectral range 2800–6200 A have been obtained by emission and from hook measurements. Relative sets of ƒ-values were determined by combining emission measurements on a hollow cathode with hook measurements in a high-temperature furnace.

Oscillator strengths in porphyrins

Chemical Physics Letters, 1971
Abstract Oscillator strengths for D 4h and D 2h porphyrins are calculated using the dipole gradient formulation and compared with calculations employing the dipole length operator. The effect of configuration interaction is also discussed.
