Rare-earth doping changes the emission spectra of the perovskite materials, which can be divided into the blue shift, enhancement of the original perovskite luminescence and the new peak excited by the doped ions [ 61, 62, 63, 64, 65, 66 ]. The temperature and doping concentration will affect the luminescence characteristics [ 67, 68 ].
However, their inherent shortcomings, such as lack of near-infrared (NIR) photoluminescence (PL), instability and low efficiency, limit their practical applications. It is notable that doping and ion substitution represent effective strategies for tailoring the optoelectronic properties and stabilities of perovskite nanocrystals (NCs).
† Dedicated to the Special Issue of Perovskite. Rare earth (RE) ions, with abundant 4f energy level and unique electronic arrangement, are considered as substitutes for Pb 2+ in perovskite nanocrystals (PNCs), allowing for partial or complete replacement of lead and minimizing environmental impact.
Apart from the above two main application fields, Ln 3+ ions have also been reported to be used in the fields of photodetectors and luminescent solar concentrators. These indicate the huge potential of rare-earth metals in improving the performances of the perovskite optoelectronic devices.
The stock solution of SmI 3 was prepared in a mixed solvent of DMSO and N, N-dimethylformamide (DMF), the perovskite precursor solution was spread on the substrate and spun, a hot air was blown over the spinning substrate. The results showed that Sm 3+ doping could improve the high-quality surface of the perovskite.
RE ions have narrow and sharp emission peaks, and RE doped halide perovskite can produce characteristic emission of RE ions (from UV to NIR) via energy transfer, making perovskite materials further develop in the field of displays and LEDs.
