From: Tailoring exciton and excimer emission in an exfoliated ultrathin 2D metal-organic framework
Luminescence tailoring. Excitation (a), and excitation-dependent emission (b) of 2D Ca-MOF bulk crystals (inset shows the shifting tendency of CIE coordinates with different excitation wavelengths). c Schematic representation of the dual emission pathways (shown in peak-deconvolution manner) of Ca-MOF bulk crystal and nanosphere samples: interlayer excitons-related emission (blue dash) and intralayer excimers-related emission (red dash), and tuning off the former by cutting down layered structures in nanosheet and nanobelt samples by exfoliation and morphology transformation
