Abstract

Because of their tunable bandgap, wide visible emission wavelength, and high photoluminescence quantum yield and mobility, perovskite quantum dots (PQDs) have potential in various applications, such as in light emitting diodes, sensors, and photodetectors. However, the poor phase stability of PQDs in the environmental atmosphere impedes their further application. Therefore, encapsulation is important because it enhances PQD stability, with electrospinning (ES) being a versatile encapsulation method. This study investigated recent developments in ES-encapsulation size confinement for organic/inorganic hybrid OIPQDs (CH₃NH₃PbX₃; X = Cl, Br, I) and inorganic IPQDs (CsPbX₃; X = Cl, Br, I). ES fibrous systems greatly decrease perovskite size while retaining their shape and without forming aggregates; this facilitates superior photoluminescence (PL) emissiveness and stability.
