Spectral characterization of long-lived luminescence in h-BN nanopowder under UV excitation
I. A. Weinstein, D. M. Spiridonov, A. S. Vokhmintsev +1
Photoluminescence (PL) features of nanostructured h-BN powder are studied in the range of 200-600 nm in millisecond time window. It is found that four PL excitation bands of 4.58,…

Temperature effects in luminescence of associated oxygen-carbon pairs in hexagonal boron nitride under direct optical excitation within 7-1100 K range
A. S. Vokhmintsev, I. A. Weinstein
We have studied the temperature dependencies of the photoluminescence (PL) intensity of 4.1 eV in microcrystalline powder of hexagonal boron nitride in the range of 7-1100 K. The r…
