光功能导向的SiNN分子电致发光特性研究
The electroluminescence properties of the light function-oriented diazasilene(SiNN)molecule
摘要
Abstract
This work adopts the density functional B3P86/cc-PVTZ method to optimize the ground state structure and the time dependent density functional theory TDDFT/cc-PVTZ to study the absorption spectra, excitation energies and oscillator strength of diazasilene molecule SiNN under different external electric fields. The results show that the absorption spectra, excitation energies and oscillator strengths of SiNN molecule are affected strongly by the external electric fields. The important results are that the SiNN molecule has a violet light absorption spectrum about 376~401 nm region under a certain external electric fields. Also, the luminescence mechanism of visible light for SiNN molecule is investigated. It is fond that the calculated emission spectra located in visible light region are in good agreement with experimental data.关键词
