In stable condition : Highly luminescent and stable CdSe clusters show optical properties similar to those of molecules rather than nanocrystals (e.g., the photoluminescence (PL) lifetime, see picture). The synthesis of (CdSe) 33,34 clusters is thermodynamically preferred. These “magic‐sized” clusters could be used as uniform building blocks for optoelectronic nanodevices.
