Title
(EN) Semiconductor nanocrystal particle and production methods thereof
Abstract
(EN)

A semiconductor nanocrystal particle represented by Chemical Formula 1 and having a full width at half maximum (FWHM) of less than or equal to about 30 nanometers (nm) in the emission wavelength spectrum is provided:
AxA′(3+α−x)D(2+β)E(9+γ).  Chemical Formula 1
In Chemical Formula 1, A is a first metal including Rb, Cs, or a combination thereof, A′ is an organic substance derived from an ammonium salt, an organic material derived from an organic ligand, or an organic material including a combination thereof, D is a second metal including Sb, Bi, or a combination thereof E is Cl, Br, I, or a combination thereof, 1<x≤3, −1<α<1, 3+α−x>0, −1<β<1, and −1<γ<1.
