“…88 Similar to the variety of stimuli influencing biological synapses, synaptic devices can also be triggered by several kinds of input signals, such as electrical pulses (varying magnitude, frequency, and duration of voltage pulses, including specific voltage patterns), photonic pulses (modulating amplitude and wavelength), chemical stimulus (using specific molecules or ions), etc., depending on the particular design and functionalities of the devices. 18,19,76,[89][90][91] The synergy between the electronic and photonic stimuli in synaptic devices enhances their capabilities in terms of speed, efficiency, adaptability, and parallelism. In particular, the research on optoelectronic synaptic devices to create artificial synapses is focused primarily on novel materials and device architectures.…”

“…An overview of various synaptic functionalities could be found in the references. [29,56] Although most examples of memory functionality (learning and forgetting) have been demonstrated using electrically stimulated devices, an interesting prospect is the realization of optical neuromorphic memory and neural emulation (Figure 2c). Several studies have shown that both memory and forgetting can be stimulated by pulse trains, with the efficacy (memory level and retention time) correlated with the intensity, duration, and quantity of the pulses.…”

Metal halide perovskite based materials have emerged over the past few decades as remarkable solution‐processable optoelectronic materials with many intriguing properties and potential applications. These emerging materials have recently been considered for their promise in low‐energy memory and information processing applications. In particular, their large optical cross‐sections, high photoconductance contrast, large carrier‐diffusion lengths, and mixed electronic/ionic transport mechanisms are attractive for enabling memory elements and neuromorphic devices that are written and/or read in the optical domain. Here, recent progress toward memory and neuromorphic functionality in metal halide perovskite materials and devices where photons are used as a critical degree of freedom for switching, memory, and neuromorphic functionality is reviewed.

“…2022, 32, 2206040 the brain is seen as a highly attractive topic for the application of in-memory computing. [56][57][58][59][60][61] The behavior of floating-gate photomemory actually is similar to the synaptic transmission process, where the transmission will take place as there is an action potential triggered by a light signal. When the light signal is received, the neurotransmitter will be released from the pre-synaptic neuron, cross the synaptic cleft, and then received by the post-synaptic neuron.…”

Phosphorescent materials have received considerable attention in organic solar cells (OSCs) due to their long emission lifetime and inhibited geminate recombination. Motivated by its particular photophysical property, herein, the spatially addressable bis(2‐benzo[b]thiophen‐2‐ylpyridine)(acetylacetonate)iridium(III) (Ir(bt)2(acac))/polystyrene‐b‐poly(4‐vinylpyridine) (PS‐b‐P4VP) as a photoactive floating‐gate is first demonstrated to explore the application of phosphorescent material on the photo‐responsive characteristics of photomemory and artificial photonic synapse. By manipulating the interfacial area between Ir(bt)2(acac)/PS‐b‐P4VP and active channel by a solvent annealing process, an ON/OFF current ratio of 103 and a low programming time of 700 ms can be achieved. The current study addresses the exciton lifetime of photoactive material functions in photomemory and highlights the interfacial area between photoactive materials and charge‐carrier transporting materials in reducing photo‐programming time.
