Popis: To gain an insight into the lattice and band structure of blue perovskite NC emitters, doping organic cations (FA+) reduces nonradiative recombination at room temperature. The FA+ significantly decreases exciton quenching and phonon energy scattering via manipulating hot carriers and electron filling in band structure.
