Since several years, optical properties of semiconductors, and especially of UV emitting materials, have been extensively studied because of their potential use in optoelectronics. In that purpose, studying optical properties of hexagonal boron nitride (hBN) and boron nitride nanotubes is of particular interest since they are both wide band gap semiconductors (~6 eV).The purpose of this work is to analyze the optical properties of these materials and, more precisely, their excitonic effects by developing optical characterization methods dedicated to observe UV emissions.The experimental techniques we have developed (photoluminescence and cathodoluminescence) have allowed us understanding luminescence properties of hBN. Thus, we have observe...
