The interesting luminescence behavior and rare nonlinear optical properties of the {Ag55Mo6} nanocluster†
Abstract
The remarkably reversible thermochromic luminescence behavior and the rare nonlinear optical (NLO) properties of the [Ag55(MoO4)6(CCtBu)24(CH3COO)18(CH3COO)]·2H2O ({Ag55Mo6} for short) nanocluster reported were investigated experimentally. The important contributions of Ag+, C
C− ions and MoO42− groups to the NLO properties were proved by further density functional theory (DFT) calculations.
