Laser image recording on detonation nanodiamond films

Abstract

A focused He – Ne laser beam is shown to cause local blackening of semitransparent detonation nanodiamond (DND) films at incident power densities above . Data obtained with a Raman spectrometer and low-power laser source indicate that the blackening is accompanied by a decrease in broadband background luminescence and emergence of sharp Raman peaks corresponding to the structures of nanodiamond and carbon. The feasibility of image recording on DND films by a focused He – Ne laser beam is demonstrated.
