We
have carried out laser-induced fluorescence measurements of hBN powder
at room temperature under different environmental conditions (dry powder
and suspensions in water or ethanol). From fluorescence excitation
spectra, the absorption onset, related to the bandgap energy of this
indirect gap semiconductor, has been precisely determined to be E
g=4.02卤0.01 eV. This result is of importance in view of large
discrepancies in previously
