摘　　要：In this work,we study the optical properties of a class of magnetically charged rotating black hole spacetimes.The black holes in question are assumed to be immersed in the quintessence field,and subsequently,the resulting black hole shadows are expected to be modified by the presence of dark energy.We investigate the photon region and the black hole shadow,especially their dependence on the relevant physical conditions,such as the quintessence state parameter,angular momentum,and magnetic charge magnitude.The photon regions depend sensitively on the horizon structure and possess intricate features.Moreover,from the viewpoint of a static observer,we explore a few observables,especially those associated with the distortion of the observed black hole shadows.
