Ensuring information security has emerged as a paramount concern in contemporary human society. Substantial advancements this regard can be achieved by leveraging photonic signals the primary carriers, utilizing logical gates capable of wavelength tunability across various time and spatial domains. However, challenge remains rational design materials possessing space-time-color multiple-resolution capabilities. In work, facile approach is proposed for crafting metal-organic halides (MOHs) that offer resolution. These MOHs integrate time-resolved room temperature phosphorescence color-resolved excitation dependencies with both space-resolved ex situ optical waveguides heterojunctions. Capitalizing on these multifaceted properties, MOHs-based two-dimensional (2D) heterojunctions exhibit ability to tune full-color emissions spectra from blue red, operating within different temporal scales. Therefore, work introduces an effective methodology engineering resolved MOH microstructures, holding significant promise development high-density devices.
