Abstract: This research paper delves into the synthesis and characterization of luminescent rare-earth-doped perovskitenanocrystals, aiming to enhance their application in bioimaging. Recognizing a significant gap in the tailored optimization of these nanocrystals for bioimaging purposes, the study sets out to systematically investigate the influence of synthesis parameters on their photoluminescence quantum yield (PLQY), a critical factor for bioimaging efficacy. Employing a quantitative research design, the methodology encompasses the experimental synthesis of nanocrystals doped with selected rare-earth ions (Eu3+ and Tb3+), followed by an in-depth analysis of their optical properties under varying conditions such as dopant concentration, synthesis temperature, annealing time, solvent choice, and perovskite host composition.
Key findings reveal that the PLQY of these nanocrystals can be significantly enhanced by optimizing the mentioned parameters, with the highest luminescent efficiency observed at a 5% doping level, a synthesis temperature of 150°C, and post-synthesis annealing. DMSO was identified as the superior solvent for facilitating higher PLQY, and the CsPb(ClBr)3 host composition emerged as the most conducive to luminescence. These results not only fill a crucial literature gap by providing targeted insights into the synthesis of perovskitenanocrystals for bioimaging but also underscore the potential of these materials in advancing diagnostic imaging technologies. The implications of this research extend beyond bioimaging, suggesting applications in the broader field of photonic devices and highlighting the intersection of material science and biomedical research.
