Similar Prenucleation Clusters in Hot-Injection and Heating-Up Approaches to CdS Colloidal Semiconductor Quantum Dots
and STDO (sulfur powder dissolved in TDO). Furthermore, we reveal that the preformed PNC disappeared faster at a higher temperature and QDs emerged. When PNC-containing samples from the two reactions were dispersed at room temperature, magic-size clusters (MSC-311 displaying optical absorption peaking at ∼311 nm) developed. Accordingly, we conclude that the two-step model proposed by Yu provides more precise explanations to the N/G of QDs and the appearance of MSCs than the LaMer model does.
