Abstract: The work presents a synthesis method, structural and optical characteristics as well as a comparative analysis of properties of colloidal quantum dots based on halide perovskites doped with Nd³⁺ ions with 20% substitution of lead ions. Nanocrystals with a controlled content of a rare-earth element were synthesized by a hot injection method, which ensured the production of stable colloidal structures with a specified level of doping. The structural analysis using an auto-emission scanning electron microscope confirmed the polycrystalline nature of the nanoparticles with the grain size of ~30 to 200 nm. The elemental composition corresponds to the initial materials, which indicates the controllability of the doping process. The quantum yield of photoluminescence was 40%, which is a high value for Nd-doped perovskite systems. The emission spectrum with a maximum at 458 nm shows a pronounced blue shift due to the effect of Nd³⁺ on the band gap. Diluted dispersions are recommended to obtain reliable spectral data. The obtained results confirm the effectiveness of the proposed approach and open up prospects for the application of doped perovskite nanocrystals in optoelectronics, photonics, and scintillation technologies.
