Abstract
The colloidal synthesis of halide perovskite quantum dots has been extensively studied due to their superior optical properties. However, synthesizing stable iodide-based perovskite quantum dots continues to pose challenges. In this work, by choosing an alternative solvent among several preferences such as dimethylformamide (DMF), dimethylsulfoxide (DMSO), and acetonitrile (ACN) as a solvent to form the precursor MAPbI3, and using an antisolvent suitable for this precursor, obtaining perovskite quantum dots with a stable MAPbI3 structure was achieved. The synthesized MAPbI3 perovskite quantum dots were found to maintain their bright red luminescence for over 8 months. The spectral properties of synthesized MAPbI3 quantum dots were investigated using electronic absorption and fluorescence spectroscopies.
期刊介绍：
Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
