摘要：

We investigate the excitation energy dependence of the boron K soft-x-ray emission of B2O3 and hexagonal-BN using synchrotron radiation. When exciting into the core exciton state the spectra are shifted to lower energy by 1.5 and 1.8 eV, respectively. This shift is found to be a result of phonon relaxation and differences in initial- and final-state electronic screening.
