A team of scientists from the University of California, Los Angeles have developed a new way to create two-dimensional (2D) nanosheets that are highly tunable and have a wide-range of potential applications, such as optoelectronic devices for use in solar cells. The research, published in the journal Nature Materials, details a new method of creating nanosheets from lead halide perovskites that can be easily tuned to generate any desired bandgap. This breakthrough could enable the creation of more efficient optical and electronic devices, such as solar cells and lasers. The researchers found that they could create nanosheets with different bandgaps simply by changing the thickness of the nanosheets and the amount of halide ions in the perovskite material. This discovery provides a powerful new tool for controlling the optical and electronic properties of nanosheets. The team is now working to further explore the potential applications of their new nanosheets.
