Spectral properties of B₄₀ enhanced by small molecule adsorption.

ABSTRACT: The luminescence characteristics of small molecule excited B₄₀ have not been studied yet, and it may have a potential application value in quantum dot luminescence. Herein, the adsorption and fluorescence emission spectra of small molecules (pyridine, pyrazine and benzene) adsorbed on B₄₀ are studied using first-principles. The results show that the absorption of pyridine and pyrazine on B₄₀ can form stable chemisorption structures pyridine-B₄₀ and pyrazine-B₄₀, while benzene adsorption can form physisorption structure benzene-B₄₀. Moreover, the adsorbed pyridine can enhance the intensity of emission spectra of B₄₀. And the pyrazine adsorbed can obviously enhance the intensity of absorption and emission spectra of
