Special Issue Information

Dear Colleagues,

Quantum dots (QDs) are unique material structures in which the carriers are three-dimensionally confined and the intrinsic properties are altered by quantum confinement effects, which are exploited by controlling their size. The QDs research field has been a hot topic in fundamental studies for several decades and has found applications in various fields, including displays, illuminations, renewable energy devices, photodiodes, photoresists, image sensors, biomedical applications, and so on. With the mass production of QDs and further understanding of their photophysical and photochemical properties, many industries have been involved in the development of quantum-dot device techniques and will open a market in this field.

This Special Issue aims to provide recent, informative, QD-related resources for readers by addressing a broad range of topics, from QD materials chemistry and characterization to processing and device fabrication. It will focus not only on the synthesis of QD materials with various compositions, such as II–VI, III–V, perovskite, and carbon families; core/shell hetero-structural engineering; and surface modification/encapsulation; but also on their versatile applications, such as down-conversion-based and electroluminescence-based light-emitting diodes for display/lighting devices; luminescent solar concentrators; and biological labels.

We believe that this Special Issue on QDs will provide an opportunity to circulate innovative ideas and technologies on these emerging topics and contribute to the dissemination of expertise for young and leading researchers in the QD-related field.

Cerium is a rare-earth metal commonly used as a dopant in various metal oxides to enhance their performances or provide optoelectronic properties. Cerium oxide (ceria) is particularly valuable owing to its unique properties and applications in various fields, such as biomedical research, photovoltaics, and industrial catalytic processes. This review focuses on the use of cerium and ceria doping in the synthesis of SiO2 and ZnO. Studies have shown that Ce-doped SiO2 thin films exhibit luminescence properties and proton shielding capabilities, and that Ce-doped ZnO has potential applications in gas sensors. In this review, we highlight the potential for controlling the luminescence and optical characteristics of these materials via cerium doping, opening up possibilities for various technological advancements and potential applications of cosmic ray shielding in space photovoltaics.
