Recently, it became possible to synthesize nanocrystals of this material as well. Interestingly; simply by controlling the size and shape of these crystals, new aspects of this material literally came to light. These nanocrystals have proven to be interesting candidates for light emission. .. In this thesis, the recombination, dephasing and diffusion of excitons in perovskite nanocrystals is investigated using time-resolved spectroscopy. All these dynamic processes have a direct impact on the light-emitting device performance from a technology point of view. However, most importantly, the insights gained from the measurements allowed the author to modify the nanocrystals such that they emitted with an unprecedented quantum yield in the blue spectral range, resulting in the successful implementation of this material as theactive layer in an LED. This represents a technological breakthrough, because efficient perovskite light emitters in this wavelength range did not exist before.. | | 出版日期 | Book 2021 | | 关键词 | Perovskite Nanocrystals; Lead Halide Perovskites; High Photoluminescence Quantum Yield; Blue light emit | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-030-70940-2 | | isbn_softcover | 978-3-030-70942-6 | | isbn_ebook | 978-3-030-70940-2Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerl |
