the radius (not the diameter) of the particle by half a lattice parameter.
Many publications also state that the amount of shell precursor is
calculated once the core particles have been prepared, although few
state how. Two models exist

— the more common and easiest to use is

the concentric shell model, rst described by Dabbousi et al. , 28 where

the volume of progressive concentric shells is estimated volumetrically,
then worked backwards through the bulk densities to the number of
ions required to grow the

rst, shell, then the second, etc. The unit cell
model utilises bulk lattices parameters to calculate the number of
atoms required for each monolayer using standard crystallography
programs such as crystal maker. An excellent description of the above
is given in J. L. van Embden
