The future of energy might be tiny — very tiny. Measuring at roughly 1/10, 000 the width of a human hair, semiconductor nanocrystals emit tunable light and can exhibit quantum features.


As continued climate change necessitates more sustainable and more efficient energy, researchers are diving deeper into understanding and exploiting the unique properties of nanocrystals, including how to synthesize variations to overcome limitations.


To highlight recent advances made with regard to nanocrystals exhibiting a specific crystalline structure known as perovskite, Energy Material Advances, a Science Partner Journal, published its first special issue on February 2022. The issue features six research articles and two review papers, authored by scientists from nine countries.


“The world is facing the grand challenges of balancing economic growth and environmental protection, urging the development of sustainable energy sources and more efficient energy consumption,” said journal editor Hongbo Li, professor in the Beijing Key Laboratory of Construction-Tailorable Advanced Functional, Materials and Green Applications, Experimental Center of Advanced Materials School of Materials Science and Engineering, Beijing Institute of Technology. “To tackle these challenges, new materials are in great demand. In the past few years, perovskite and perovskite analogues have emerged as important nanocrystal materials for their unique features, such as defect tolerance, emission color purity, tunable band gap and intriguing charge exciton transport behavior.”


Perovskite nanocrystals typically comprise an ABX3 structure, where A and B are positively charged ions and X is negatively charged and bonds to both A and B. Named for a natural mineral exhibiting the same structure, perovskite nanocrystals are bright emitters and relatively easy to synthesize. Such nanocrystals have been extensively studied and applied to artificial lighting, displays, solar cells, photodetectors and even biomedical areas, according to Li.


“Significant efforts have been devoted to the investigation of perovskite materials with novel compositions and structure for a variety of optoelectronic devices,” Li said. “In light of the impact of perovskite nanocrystals and their rapidly growing community, the special issue focuses on emerging topics in this area including, but not limited to, perovskite and perovskite analogue semiconductor nanocrystals with novel structures and properties, and their application in light-emitting diodes, solar cells and radiation detectors.”


The issue consists of two review articles and six research papers, focusing on the most recent developments in synthesizing and tuning perovskite nanocrystals and other emerging nanocrystal materials. The topics covered range from fundamental understanding of doping, synthesis and spectroscopy to the application of nanocrystals in solar cells and light-emitting diodes, or LEDs.


“Overall, this special issue reviews the exciting progress in various fields of nanocrystals and presents the frontier of nanocrystal-related research from many leading groups around the world,” Li said. “We are very much grateful to all the authors for their contributions to this exciting issue. We also thank all reviewers and the editorial board for organizing this special issue.”


Guest editors on the special issue include Liberato Mann, Nanochemistry Department, Istituto Italiano di Tecnologia, Italy; Osman M. Bakr, Advanced Membranes and Porous Materials Center, KAUST Catalysis Center, Division of Phsyical Science and Engineering, King Abdullah University of Science and Technology, Saudi Arabia; and Sergio Brovelli, Dipartimento di Scienza dei Materiali, Università degli Studi di Milano-Bicocca, Italy.
