考虑到纳米团簇的大小对其光学能隙的显著影响，本文利用解组装的概念来呈现光致发光发射的蓝移以及组装的M-25纳米团簇的量子产率（QY）的增强。解组装将组装的M-13-二聚体Pt 2Ag 23（PPh）（10）Cl-7通过Pt 1Ag 24（SPhMe 2）（18）纳米簇分裂成单一的M-13-核Pt 1Ag 12（dppm）（5）（SPhMe 2）（2）。
Considering the significant effect of the size of a nanocluster on its optical energy gap, we herein exploit the concept of de-assembly to render a blue-shift of the photoluminescent emission as well as an enhancement of the quantum yield (QY) of assembled M-25 nanoclusters. The de-assembly splits an assembled M-13-dimer Pt2Ag23(PPh)(10)Cl-7 into a sole-M-13-kernel Pt1Ag12(dppm)(5)(SPhMe2)(2), via a Pt1Ag24(SPhMe2)(18) nanocluster.
