RT Journal Article T1 Luminescence Study of Structural-Changes Induced by Laser Cutting in Diamond Films A1 Cremades Rodríguez, Ana Isabel A1 Piqueras de Noriega, Javier AB The effect of laser cutting on the structure of a chemical vapor deposited diamond film has been investigated by cathodoluminescence (CL) in the scanning electron microscope. The variation of particle morphology and CL spectra as a function of the distance to the cutting edge is described and possible laser induced structural changes are discussed. At the damaged region total CL emission increases and nitrogen-vacancy centers are detected.
