The results of the quantitative Raman analysis, performed on multi‐walled carbon nanotubes produced by iron‐catalysed chemical vapour deposition, are utilised for deriving a scaling law for the growth parameters. A semi‐empirical approach, already successfully applied to different materials and growth techniques, is utilised and demonstration is given that the reaction outcome, in terms of yield to C deposits and crystalline perfection of nanotubes attained, analytically depends on the growth parameters through a single dimensionless combination of them.
