Ln3+-doped glasses: Advancing molecular logic for integration into photonic and electronic devices

The rapid miniaturization of electronic devices has pushed the limits of conventional silicon-based technologies, creating a pressing need for novel approaches to sustain the exponential growth of computing power. This study explores the innovative application of Ln³⁺-doped glasses in developing molecular logic systems as a potential solution. Exploiting Eu³⁺ and Dy³⁺, we investigated the luminescence properties under various physical stimuli such as excitation wavelength and temperature. Our findings reveal the capability to construct logic elements of varying complexity, from simple AND and OR gates to advanced FULL-ADDER and FULL-SUBTRACTOR circuits. This work represents the first instance of using Ln³⁺ exclusively for molecular logic via physical stimuli. The robust and stable optical properties of the doped glasses enable their integration into conventional electronic and photonic devices, potentially revolutionizing the landscape of molecular logic and computing. This research not only enhances the understanding of light-matter interactions in Ln³⁺-doped systems but also opens new pathways for the development of miniaturized, high-performance innovative computational devices.
