This work reports the synthesis of high-quality CsPbBr3 quantum dots (QDs) via an octylammonium bromide (OABr)-assisted ligand-assisted reprecipitation (LARP) method and the systematic tuning of their optical properties. The as-prepared QDs exhibit clear quantum-confinement features, with absorption edges located at ~510-520 nm and narrow photoluminescence (PL) peaks in the range of ~491-518 nm. By varying the ligand-to-precursor ratio from 3:5 to 12:10:5:2000, the polydispersity and emission intensity of the QDs can be effectively controlled. Increased ligand content improves surface passivation, resulting in smoother absorption spectra and enhanced optical stability. Furthermore, embedding the QDs into a PMMA matrix induces pronounced blue shifts (~14-26 nm), which are attributed to reduced aggregation and interfacial interactions between the nanocrystals and the polymer host. The optimised CsPbBr3 QD/PMMA composites exhibit high photoluminescence efficiency and tunable emission characteristics, highlighting their strong potential as luminescent materials for luminescent solar concentrator (LSC) applications.
