The miniaturization of the silicon chips is reaching its physical limits, and the transistors are so small that current leakage will become an insurmountable problem. Additionally, the actual chip shortage makes clear the excessive world dependence on silicon, stressing the need for silicon‐free computing strategies. Quantum computing process information by manipulating photons, and computation performed by individual molecules are being proposed as alternatives, with potential benefits in terms of miniaturization, performance enhancement, and energy efficiency. Molecular logics can play a decisive role in the future of the computer industry, and the unique photonic characteristics of trivalent lanthanide ions make them suitable candidates to integrate future molecular logic applications. In this work, a Eu3+/Tb3+ co‐doped organic–inorganic hybrid is presented as an illustrative all‐photonic logic platform constructed through the decay dynamics of both lanthanide and hybrid host emissions. Besides combinatory AND, NAND, and INH logic gates, this system presents on‐choice Eu3+, Tb3+, or host emission enabling the development of reprogrammable and reconfigurable photonic molecular logic gates. All‐photonic temperature‐reprogrammable changes from AND to INH logic gates and a reconfiguration among INH and AND1 or AND2 gates, based on the excitation wavelength are demonstrated, showing a clear step forward toward mirroring electronic logic counterparts.

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 Eu 3+ /Tb 3+ 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 Eu 3+ and Tb 3+ 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.

The design of molecular materials suitable for disparate fields could lead to new advances in engineering applications. In this work, a series of Ln3+-doped BiF3 sub-microparticles were synthesized through microwave-assisted synthesis. The effects of doping are evaluated from the structural and morphological viewpoint. In general, increasing the Ln3+ concentration the octahedral habitus is distorted to a spheric one, and some aggregates are visible without any differences in the crystalline phase. The optical response of the samples confirms that the BiF3 materials are suitable hosts for the luminescence of the tested trivalent lanthanide (Ln3+) ions (Ln = Eu, Tb, Tm, Ho, Er, Yb). A Yb3+/Er3+ co-doped sample is presented as an illustrative example of all-photonic molecular logic operations and primary luminescent thermometry.
