Special Issue Information

Dear Colleagues,

The rapid advancement of nanomaterials has opened new opportunities in optoelectronic technologies, enabling major improvements in efficiency, tunability, and integration. These developments have expanded the scope of devices such as photodetectors, solar cells, LEDs, lasers, and optical sensors.

This Special Issue, Nanomaterials for Optoelectronic Devices: Synthesis, Properties, and Applications, invites original research articles, review papers, theoretical studies, and perspectives on the synthesis, characterization, and application of advanced nanomaterials—including quantum dots, nanocrystals, 2D materials, and hybrid heterostructures—for modern optoelectronic systems.

We welcome submissions on scalable fabrication techniques (e.g., solution processing, PVD, CVD, ALD), surface and interface engineering, charge transport, exciton dynamics, and light–matter interaction. Studies addressing challenges such as long-term stability, eco-friendly processing, and large-scale integration are strongly encouraged.

In addition to traditional optoelectronic applications, we also invite work on light-driven photocatalysis, photoelectrochemical systems, bio-integrated optoelectronics, neuromorphic devices, and nanophotonics for quantum sensing and communication.

This Special Issue aims to highlight innovative approaches that connect fundamental research with real-world device technologies. Contributions from a broad range of disciplines are encouraged to promote cross-cutting advances in nanomaterial-enabled optoelectronics.

We look forward to receiving your contributions.

Quantum sensing with nitrogen vacancy (NV) defects in diamond enables detection of extremely small changes in temperature, host material strain, and magnetic and electric fields. Action potential detection has previously been demonstrated with cardiac tissue and whole organisms using NV defects in bulk diamond crystals. Nanodiamonds (NDs) with NV defects were previously used as effective fluorescent markers, as they do not bleach under laser illumination like conventional fluorescent dyes. Subcellular-level action potential recording with NDs is yet to be demonstrated. Here, we report our results on the confocal imaging of NDs and the feasibility of optically detected magnetic resonance (ODMR) experiments with Cath.-a-differentiated (CAD) mouse brain cells. 10 nm and 60 nm NDs were shown to diffuse into cells within 30 min with no additional surface modification, as confirmed with confocal imaging. In contrast, 100 nm and 140 nm NDs were observed to remain localized on the cell surface. ND photoluminescence (PL) signals did not bleach over the course of 5 h long imaging studies. ODMR technique was used to detect externally applied millitesla-level magnetic fields with NDs in cell solutions. In summary, NDs were shown to be effective, non-bleaching fluorescent markers in mouse brain cells, with further potential for use in action potential recording at the subcellular level. Full article

Abstract
The earth-abundant, ecologically friendly structure of kesterite Cu2ZnSn(S,Se)4 (CZTSe) solar cells, with their advantageous optoelectronic characteristics, including a direct bandgap (1.0–1.5 eV) and a high optical absorption coefficient (>104 cm−1), have made them a very promising member [...] Read more.
The earth-abundant, ecologically friendly structure of kesterite Cu2ZnSn(S,Se)4 (CZTSe) solar cells, with their advantageous optoelectronic characteristics, including a direct bandgap (1.0–1.5 eV) and a high optical absorption coefficient (>104 cm−1), have made them a very promising member of thin-film photovoltaics. However, the path toward commercialization has been slowed down by restraint such as high open-circuit voltage deficits, deep-level defect states, and compositional inhomogeneities that lead to charge recombination and efficiency loss. Despite these obstacles, very recent advances in material processing and device engineering have revitalized this technology. Incorporating elements like Ge, Ag, and Li; optimizing interface properties; and introducing methods like hydrogen-assisted selenization have all contributed to raising device efficiencies by around 15%. This review discusses recent progress and evaluates how far CZTSSe has come and what remains to be done to realize its commercial promise. Full article
