Luminescence spectra of the molecule B _L at the bias voltage V _bias = 1.8 V. Insets: red solid and green dotted lines show luminescence spectra for vibrational state in nonequilibrium and thermal equilibrium, respectively. Here, (a) T_pl = 10^-4 and $\hslash {\omega }_p=2.05\text{eV}$, (b) T_pl = 10^-2 and $\hslash {\omega }_p=2.05\text{eV}$, (c) T_pl = 10^-4 and $\hslash {\omega }_p=1.25\text{eV}$, and (d) T_pl = 10^-2 and $\hslash {\omega }_p=1.25\text{eV}$. The exciton-plasmon coupling is V = 0.10 eV.
