To deeply understand transformation pathways of MSCs and control their composition\/stability are essential to form large\u2010scale high quality QDs with mono\u2010dispersity and enhanced optical properties. However, the transformation pathway of ionic compound semiconductor MSCs with weak bond binding energy have rarely been investigated. In this work, taking ionic CsPbBr\n                    <jats:sub>3<\/jats:sub>\n                    MSCs as a representative model system, we here report both thermally\u2010induced direct (Pathway 3) and precursor compounds (PCs) assisted (Pathway 1) transformation between binary PbBr\n                    <jats:sub>2<\/jats:sub>\n                    MSCs (absorption centered at \u223c390\u00a0nm) and ternary CsPbBr\n                    <jats:sub>3<\/jats:sub>\n                    MSCs (absorption centered at \u223c415\u00a0nm) at sub\u2010ambient temperature, which have been first illustrated in ionic perovskite MSCs systems. Moreover, when increasing reaction temperature to 80\u00b0C, MSC\u2010415 dissociate into monomers\/fragments (Pathway 2) to form larger sized nanocrystals (NCs). In addition, the compositions and structures of MSCs have been experimentally and theoretically studied. This work contributes to fundamental understandings of transformation mechanism of perovskite MSCs\/NCs systems, which is beneficial to synthesize size\u2010 and composition\u2010controlled colloidal semiconductor QDs and NCs with tailored optical properties.\n                  <\/jats:p>","DOI":"10.1002\/smll.202513617","type":"journal-article","created":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T21:25:16Z","timestamp":1773005116000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Unraveling Transformation Pathways of Colloidal Semiconductor Perovskite Magic\u2010Sized Clusters at Sub\u2010Ambient Temperature"],"prefix":"10.1002","volume":"22","author":[{"given":"Yueling","family":"Lai","sequence":"first","affiliation":[{"name":"College of Materials Science and Engineering Sichuan University  Chengdu P.
