Abstract

Two-dimensional laser induced fluorescence measurements are applied tothe chemical vapor deposition of diamond by an oxyacetylene flame. Thefluorescence distributions of C₂, CH, and OH are measured forvarious deposition conditions. The influence of the temperature of themolybdenum substrate and the distance between the substrate and theflame front on the two-dimensional distributions and on the quality andmorphology of the deposited diamond is investigated. A relation isobserved between the C₂ distribution in the flame and thelocal growth rate and quality of the diamond layer, thereforeC₂ is thought to be an important species for diamond growth.The exact role of CH as a growth species is less clear; OH seems to beof minor importance. All measurements are performed during diamonddeposition.
