The geometric parameters characterization and ground state energies of (ZnO)6 nanoclusters were calculated using Density Functional Theory (DFT) with B3LYP and LanL2DZ basis set. Excited state energies, as well as absorption wavelength, were computed using Time Dependent-Density Functional Theory (TDDFT) for both nanostructures in its pristine form and also for variants of these nanoclusters with sulfur applied as substitutional impurity at different locations within the structure. For the emission wavelength, the excited state geometry optimization was carried out with Hartree–Fock Configuration Interaction Singles (HF/CIS). Our theoretical results are new data related to the geometry as well as to the spectral absorption/emission properties of these novel nanostructures. These cluster variants present characteristics interesting for solar cells and optical applications that will be useful for future theoretical/ experimental developments. 原文見附件 |

| (氧化鋅,ZnO)6納米微粒幾何參數(shù)表征和基態(tài)能量計(jì)算利用密度泛函理論(Density Functional Theory,DFT)B3LYP方法,取LANL2DZ基組。對(duì)兩種原始形式的納米結(jié)構(gòu)及其結(jié)構(gòu)內(nèi)的不同位置應(yīng)用硫作為取代參雜的納米異型微粒,激發(fā)態(tài)能量以及吸收波長(zhǎng)計(jì)算采用時(shí)間依賴性密度泛函理論(TDDFT)。用于計(jì)算發(fā)射波長(zhǎng)激發(fā)態(tài)幾何優(yōu)化采用Hartree–Fock 組態(tài)相互作用方法(HF/CIS)。我們關(guān)于上述參數(shù)的理論結(jié)果既與新型納米微粒的幾何形狀有關(guān),也與其光譜吸收/發(fā)射性質(zhì)有關(guān)。上述眾多異型微粒呈現(xiàn)的眾多特性引起了將其應(yīng)用于太陽能電池和光學(xué)的興趣,上述微粒在這些方面的應(yīng)用將有助于未來理論/ 實(shí)驗(yàn)研究。 |

利用密度泛函理論(DFT)在B3LYP/LANL2DZ水平上, 對(duì)(氧化鋅)6納米晶簇的幾何參數(shù)表征和基態(tài)能量進(jìn)行了計(jì)算。對(duì)于原始的納米結(jié)構(gòu)和在結(jié)構(gòu)內(nèi)的不同位置以硫作為取代基的納米團(tuán)簇變體,使用含時(shí)密度泛函理論(TDDFT)對(duì)激發(fā)態(tài)能量和吸收波長(zhǎng)進(jìn)行計(jì)算。對(duì)于發(fā)射波長(zhǎng),其激發(fā)態(tài)幾何結(jié)構(gòu)優(yōu)化是使用hartree–fock組態(tài)相互作用(HF / CIS)完成的。我們的理論結(jié)果是新的數(shù)據(jù),這些數(shù)據(jù)既和幾何結(jié)構(gòu)有關(guān),也與這些新制備的納米結(jié)構(gòu)的光譜吸收/發(fā)射特性有關(guān)。這些納米團(tuán)簇變體在太陽能電池和光學(xué)應(yīng)用方面展現(xiàn)出的特點(diǎn),對(duì)于未來的理論和實(shí)驗(yàn)的發(fā)展是很有幫助的。 希望樓主滿意! |
