The paper investigates the properties of accretion disks around regular black holes (RBHs) derived from Einstein-nonlinear electrodynamics (NLED). The study focuses on the Dymnikova and Fan-Wang solutions, examining circular geodesics, innermost stable circular orbit (ISCO), radiative energy, temperature, and mass-to-radiation conversion efficiency. By comparing these findings with Schwarzschild black holes, significant modifications in spectral properties are observed, including increased energy emission and higher temperatures for the accretion disks. The enhanced efficiency of mass conversion into radiation is also noted, indicating that RBHs can be more efficient than Schwarzschild spacetime in this regard. The research highlights the importance of non-linear couplings between gravity and electrodynamics in shaping the physical characteristics of accretion disks around RBHs.The paper investigates the properties of accretion disks around regular black holes (RBHs) derived from Einstein-nonlinear electrodynamics (NLED).
