Feng Jiandong, Lin Zhenjin, Yang Xizhen. AN INVESTIGATION ON l.71eV LUMINESCENCE BAND IN GaP[J]. Chinese Journal of Luminescence, 1987,8(2): 121-128DOI:
A broad band peaked at 1.71eV is commonly observed in the PL spectra of
n
-GaP
[2-4
10]
. Comparing the PL spectra of epitaxial layer with that of the substrate
both have similar behaviours within the interested region. It can be concluded that the band stems from some background impurities or defects in the substrate. The shape of the broad band (Fig. 1) indicates that the band is a superposition of several bands.
