摘要
Abstract Here, the authors first report a bimetallic sulfide quantum dots (QDs)‐attached metal–organic framework (MOF) nanosheets‐based film from bisacrificial templates. By using a step by step bisacrificial templates strategy, MOF CuBDC precursors (BDC = 1,4‐benzenedicarboxylate) and chalcogenidometalates as the templates can successfully in‐situ assemble Cu 2 SnS 3 (CTS) QDs‐attached CuBDC nanosheets on the functionalized substrate (CTS @ CuBDC film). The obtained CTS QDs possess a uniform size with ≈6.2 nm and are homogeneously dispersed on MOF nanosheets, which results in an improvement of conductivity and represents a semiconductive composite film for optical application. A Z‐scan study under the excitation of a 532 nm laser shows that the CTS @ CuBDC film possesses strong optical limiting (OL) behavior and very low OL thresholds (0.92 J cm −2 ) as well as large third‐order nonlinear susceptibility (1.9 × 10 −6 esu). This work suggests that the step by step bisacrificial templates method is a fascinating and feasible strategy to prepare metal sulfide QDs dispersed MOF hybrid materials, and provides a promising potential candidate for nonlinear optical applications.
