Special Issue Information

Dear Colleagues,

Perovskite nanomaterials have emerged as highly promising candidates for optoelectronic devices and sensors due to their exceptional properties. These materials exhibit remarkable optoelectronic performance, enabling their application in various technologies. In the realm of optoelectronic devices, perovskite nanomaterials have demonstrated outstanding performance in solar cells, light-emitting diodes (LEDs), and lasers. They possess high absorption coefficients, efficient charge carrier transport, and tunable emission wavelengths, allowing for the development of efficient solar cells, vibrant LEDs, sensitive photodetectors, and coherent lasers. Moreover, perovskite nanomaterials have been utilized in sensor applications such as photodetectors, gas sensors, biosensors, and strain/pressure sensors. Their abilities to detect light across a broad range of wavelengths, interact with specific gases or biomolecules, and exhibit piezoresistive or piezoelectric properties make them versatile for sensing various analytes and conditions. Continued research and development in this field promise to improve the stability, scalability, and reliability of perovskite nanomaterials, thereby exposing their full potential in advancing optoelectronic devices and sensors.

This Special Issue welcomes high-quality reviews and experimental, theoretical, and machine learning work on optoelectronic devices and sensors for perovskite nanomaterials. Potential topics include, but are not limited to, the following:

  1. The synthesis and optical properties of perovskite and related materials;
  2. Perovskite solar cells, LEDs, and lasers;
  3. Perovskite sensors, biosensors, and photodetectors.

Organic-inorganic hybrid perovskite materials continue to attract significant interest due to their optoelectronic application. However, the degradation phenomenon associated with hybrid structures remains a challenging aspect of commercialization. To overcome the stability issue, we have assembled the methylammonium lead bromide nano islands (MNIs) on the backbone of poly-3-dodecyl-thiophene (PDT) for the first time. The structural and morphological properties of the MNI-PDT composite were confirmed with the aid of X-ray diffraction (XRD) studies, Field emission scanning electron microscope (FESEM), and X-ray photoelectron spectroscopy (XPS). The optical properties, namely absorption studies, were carried out by ultraviolet-visible spectroscopy. The fluorescent behavior is determined by photoluminescence (PL) spectroscopy. The emission peak for the MNI-PDT was observed at 536 nm. The morphology studies supported by FESEM indicated that the nano islands are completely covered on the surface of the polymer backbone, making the hybrid (MNI-PDT) stable under environmental conditions for three months. The interfacial interaction strategy developed in the present work will provide a new approach for the stabilization of hybrids for a longer time duration. Full article
