resumo
The increasing demand for computing power and downscaling is reaching the limits of the current lithographic methods, further precluding the shrinkage of the silicon chips using state-of-the-art top-down approaches. Moreover, the current chip shortage exposes the excessive world dependence on silicon, stressing the need for silicon-free computing technologies, preferably operating at the molecular level. Here, a Eu3+/Tb3+ co-doped organic-inorganic di-ureasil hybrid is used to demonstrate an illustrative example of an all-photonic device based on the emission temporal dynamics of the Eu3+ and Tb3+ ions. An all-photonic approach for temperature-reprogrammable change from a low-pass filter to a high-pass filter is reported, showing a firm step toward the design and development of molecular analogs of conventional circuit electrical passive components.
