Formation mechanism of highly luminescent silica capsules incorporating multiple hydrophobic quantum dots with various emission wavelengths

- Strategy was considered for incorporation of hydrophobic QDs into silica capsules.
- Concentration of QDs upon silanization is the key to keep the emission efficiency.
- The optimum concentration of QDs depends on their size and surface ligand.
- The PL efficiency of QDs reached over 40% after seed incorporation into silica capsules.
