Red-emissive nanocrystals of Cs4Mnx Cd1-xSb2Cl12 layered perovskites
(2022) In Nanoscale 14(2). p.305-311- Abstract
- Layered double perovskites are currently being investigated as emerging
halide-based materials for optoelectronic applications. Herein, we
present the synthesis of Cs4MnxCd1−xSb2Cl12 (0 ≤ x
≤ 1) nanocrystals (NCs). X-ray powder diffraction evidences the
retention of the same crystal structure for all the inspected
compositions; transmission electron microscopy revealed monodisperse
particles with a mean size between 10.7 nm and 12.7 nm. The absorption
spectra are mostly determined by transitions related to Sb3+, whereas Mn2+ induced a red emission in the 625–650 nm range. The photoluminescence emission... (More) - Layered double perovskites are currently being investigated as emerging

= 0.12. Finally, we demonstrate that the photoluminescence quantum
yield of the latter NCs was increased from 0.3% to 3.9% through a
post-synthesis treatment with ammonium thiocyanate. The present work
expands the knowledge of colloidal layered double perovskite
nanocrystals, stimulating future investigations of this emerging class
of materials. (Less)
