Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Bandgap-graded materials present varying spectral responses at different positions, making them possible to be used as an alternative to photoactive materials array in multi-spectral responsive devices, thus miniaturizing the apparatus. However, the preparation of bandgap-graded materials usually requires complicated deposition process. Here we report a facile low-temperature solution process to make films with lateral bandgap gradients, which form spontaneously via self-spreading and interdiffusion of solutions. We show lead halide perovskite films with MAPbCl−MAPbBr and MAPbBr−MAPbI gradients, which exhibit light absorption onsets ranging from 410 to 781 nm. The bandgap-graded films were used to make self-powered multiband photodetectors, which show different spectral responses at different positions without applying bias voltage. Furthermore, self-powered spectrometers were made by using the multiband photodetectors. [Figure not available: see fulltext.].
