Properties of the Sb:SnO₂ particles used [4].

Sb/(Sn + Sb)	Sb(III)/[Sb(III)+Sb(V)]	d(nm)		N^(b)	Powder Conductivity
at %^(a)	at %	BET^(c)	XRD^(d)	wt.% E.A.	S/cm at R.T.
0	0	8.2	7.3	0.134	1.5·10^−5
2.0	0	7.9	6.9	0.204	8.0·10^−5
7.0	0^(e)	7.1	6.5	0.282	4.5·10^−3
13.0	7.6	6.6	6.9^(f)	0.402	1.0·10^−2

^(a)Apart from Sb 0% all the Sb:SnO₂ particles are blue powders.
^(b)Present in the bulk and at the surface; at the surface as NH₃ groups.
^(c)To calculate the diameter it was assumed that the particles were spherical, non-porous and had a density of 6.99 g/cm³.
^(d)The crystallite sizes were calculated from the broadening of the peaks.
^(e)No Sb(III) were detected with XRD; IR data suggest that a very small amount of Sb(III)-OH groups are present on the surface.
^(f)Measured with TEM: 𝑑=6.3±1.1 nm.
