摘要

摘要研究了六方氮化硼在短波长光谱区的阴极发光强度在电子束激发下的变化。结果表明，在电子激发过程中，波长为 215 nm 处的峰值强度会降低，并趋于稳定值，而波长为 320 nm 处的峰值强度在电子照射下会增加。这一波段可能是在电子照射下形成的发光中心造成的。

Electron-Beam-Stimulated Formation of Luminescent Carbon Complexes in Hexagonal Boron Nitride

Abstract—

The change in the intensity of cathodoluminescence of hexagonal boron nitride in the short-wavelength spectral region upon electron beam excitation is investigated. It is shown that the intensity of the peak at a wavelength of 215 nm, associated with the band-to-band transitions, decreases during electron excitation and tends to a stationary value, whereas the intensity of the peak at 320 nm increases under electron irradiation. This band is likely caused by the formation of luminescence centers under electron irradiation.
