Recently, Professor Chen Daqin’s research team of College of Physics and Energy of FNU reported a 2D/3D heterostructure perovskite by long-chain organic halide salt post-treatment in blue perovskite light-emitting diodes (PeLEDs), and PeLEDs with tunable blue emissions (sky-blue emission at 465 nm, pure-blue emission at 475 nm, and deep-blue emission at 486 nm), featuring precise spectral tunability, ultrapure blue emissions (FWHM <15 nm), and reasonable spectral stability, were demonstrated. The work, titled “2D/3D Heterojunction Perovskite Light-Emitting Diodes with Tunable Ultrapure Blue Emissions”, was published in Nano Energy (IF = 17.882). FNU is the first organization of the paper, with Jiang Naizhong, a master candidate of FNU, as the first author, and Prof. Wang Zhibin and Prof. Chen Daqin of FNU as the corresponding authors. The work was funded by the National Natural Science Foundation of China and the Natural Science Foundation of Fujian Province.
