FIG. 1.

X-ray absorption spectra for three BN samples recorded using TEY (solid lines) and TLY (broken lines). Sample BN1 is a pure hexagonal BN powder, sample BN3 consists of pure microcrystals, and sample BN2 is predominantly high-quality microcrystals with some impurity .

FIG. 2.

XEOL from single-phase (BN1), mixed-phase BN (BN2), and single-phase (BN3). The crystalline quality of both samples is reflected in the well-resolved phonon-assisted emission peaks superimposed on the broader bands. These inhomogeneously broadened emissions are best fitted to a series of Gaussians, as indicated.

FIG. 3.

Optically detected x-ray absorption spectra for BN2 recorded at selected wavelengths: (a), (b), and (c). The band originates entirely in the surface -bonded phase in this material and is not associated with .
