Characterizations by UV, XPS and TEM.

(a) is the UV-visable absorption spectrum, transferred onto quartz substrate; (b) is the corresponding plot of ε1/2/λ versus 1/λ of (a); (c,d) are the B1s spectrum and N1s spectrum, respectively; (e) is the HR-TEM image of the h-BN film, after transferring onto Si3N4 grid and the inset image is the corresponding FFT image; (f) is the HR-TEM image of h-BN film after exposing under the electron beam for 20 seconds, showing some parallel triangle holes.
