An electron moving in an excited orbit stays there only for a very short time. 電子在激發(fā)態(tài)軌道上只能逗留很短的時(shí)間。
This will cause lasing emission wavelength to shift from ground states to excited states in QD lasers. 這將會(huì )造成量子點(diǎn)雷射的雷射發(fā)光波長(cháng)由基態(tài)轉變至激發(fā)態(tài)。
A spectral line is emitted when an atom proceeds from an excited state to a lower state. 當原子從一個(gè)受激態(tài)進(jìn)入另一個(gè)較低的狀態(tài)時(shí)，就發(fā)射一條譜線(xiàn)。
The dependence of the excitation energies of low-lying excited states on the diameters and helicity of CNT is studied. 也確認了奈米碳管的低激態(tài)態(tài)量與其半徑及螺性的關(guān)系。
