High efficiency pure blue perovskite quantum dot light-emitting diodes based on formamidinium manipulating carrier dynamics and electron state filling
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.
