Electronic and NLO characteristics of small neutral and singly charged iron-doped bismuth clusters

Insights into the nonlinear optical (NLO) response of pure Aum (2 ≥ m ≤ 7) and copper-doped Aum–xCux clusters

“…23,24 Kokabi and Salehiyoun, studied the NLO and electronic properties of small neutral and singly charged iron-doped bismuth clusters. 25 Recently, Knoppe et al studied the NLO properties of thiolate-protected and phosphine-protected Au 20 clusters. 26,27…”

“…23,24 Kokabi and Salehiyoun, studied the NLO and electronic properties of small neutral and singly charged iron-doped bismuth clusters. 25 Recently, Knoppe et al studied the NLO properties of thiolate-protected and phosphineprotected Au 20 clusters. 26,27 From the review of the valuable literature, it is evident that nano-scale materials possess excellent optical and nonlinear optical responses.…”
