Abstract
The present disclosure relates to a perovskite light-emitting composition, and a method for preparing the same. The method for producing the perovskite light-emitting composition of the present disclosure includes an organic siloxane solvent having very high hydrophobicity and low surface tension as a synthesis solvent, thereby having a large surface tension difference from the perovskite light-emitting particles containing an organic ligand. Through these properties, a dense organic ligand can be attached to the surface of the perovskite nanoparticles, and perovskite light-emitting particles having a high ligand density can be prepared. Accordingly, the perovskite light-emitting particles prepared by the method of the present disclosure have improved dispersion stability, light-emitting properties and long-term storage stability.
