Fig. 8: Bias-dependent emission spectra.

Ratio of integrated photoluminescence intensity measured under biased voltages to photoluminescence intensity measured before applied voltage as the function of time is plotted for CAIC, CABC, and Bi0.10In0.90 compounds. The void black-colored squares represent the CABC, void green-colored triangle represents the Bi0.10In0.90, and void red-colored circle represents the CAIC compounds.
