Synthesis and postsynthetic anion exchange of CsPbX₃ (X = Cl, Br, I) quantum dots
الملخص
CsPbX₃ (X = Cl, Br, I) quantum dots were synthesized using hot-injection method at various temperatures (50–200°C), resulting in quantum dots size change and corresponding photoluminescence shift. During anion exchange, continuous formation of intermediate solid solutions was observed resulting in fine adjustment of photoluminescence peak position. Dynamics of photoluminescence spectra under continuous laser irradiation for anion exchange was studied. It is necessary for anion exchange that halide should be in ionic, not molecular, form.
