From the high-energy tail of PL, we determine the electron temperature (T e) of the hot electrons. The T e variation can be explained by a model in which the longitudinal optical (LO)-phonon emission is the dominant energy relaxation process. The high-quality γ-In 2Se 3 nanorods may be a promising material for the photovoltaic devices. |
