In Situ X-Ray Scattering Study on the Formation of CsPbBr3 Perovskite Nanocrystals

An Amorphous Phase Precedes Crystallization: Unraveling the Colloidal Synthesis of Zirconium Oxide Nanocrystals

“…Small Angle X-ray Scattering Analysis. Given the success of small-angle X-ray scattering (SAXS) in delivering insights into nucleation and growth mechanisms, 10,11,14,15,21 we also take it here as a starting point in our investigation. We performed ex situ SAXS measurements on aliquots, taken from the reaction mixture at 300 °C, 320 °C, and 340 °C during the heating ramp, and at different time intervals at 340 °C.…”

“…20 SAXS revealed amorphous agglomerates in the synthesis of CsPbBr 3 nanocrystals. 21 Furthermore, magic-sized clusters with a well-defined structure have been identified in the synthesis of InP nanocrystals as intermediate species between precursors and nanocrystals. 22 Finally, the conversion of iron oleate in iron oxide nanocrystals happens without nucleation.…”

Growth methods' effect on the physical characteristics of CsPbBr3 single crystal

“…15,16 While perovskite quantum dots are often studied for device performance, understanding the optoelectronic properties of CsPbBr 3 single crystals (SCs) provides a more authentic representation. 17,18 CsPbBr 3 SCs not only excel as photodetectors but also exhibit superior stability against high-energy particles and radiation due to their lack of organic components and high atomic number. 19,20 The current literature predominantly focuses on quantum dots, nanocrystals, and thin films, underscoring the need for wellsuited CsPbBr 3 SCs for photodetector applications.…”
