PLE spectra under an excitation energy (\({E}_{ex}\)) from 1.24 to 1.77 eV at T = 10 K. The four major zero-phonon-line (ZPL) emissions are labeled as PL1(\(hh\)), PL2(\(kk\)), PL3(\(hk\)), and PL4(\(kh\)). The broad background emissions are from the phonon side bands of VSiVC and VSi. The arrow indicates one of the Raman LO and TO peaks.
