Volume fraction of CdS QDs in co-assemblies was estimated as follows:
Voleylamine-capped CdS QDs 
VPS-b - PEO 
f CdS QDs 
moleylamine
ρoleylamine

mCdS
ρCdS
mPS mPEO

ρPS ρPEO
Voleylamine-capped CdS QDs
Voleylamine-capped CdS QDs  VPS-b -PEO
where Voleylamine-capped CdS QDs, moleylamine, mCdS, VPS-b-PEO, mPS and mPEO represent volume of oleylamine-capped CdS
QDs, mass of oleylamine ligand on the surface of CdS QDs, mass of CdS, volume of block copolymer PS-bPEO, mass of PS block and mass of PEO block, respectively. moleylamine and mCdS are eatimated from
thermogravimetric analysis (TGA) result (Fig. S3), which shows that 23.4% of CdS QDs total mass is
oleylamine. The volume density of each component is: oleylamine = 0.813 g/cm3, CdS = 4.826 g/cm3, PS =
1.05 g/cm3, and PEO = 1.13 g/cm3.
