摘要：

In this paper, we study the greybody factor for static spherically symmetric black hole with non-linear electrodynamics. For this purpose, we assume minimal coupling of the scalar field and find the radial equation by using the Klein-Gordon equation. We then apply tortoise coordinate to convert this equation into Schrodinger wave equation which helps to find the effective potential. The behavior of effective potential is checked for different values of the coupling and charge parameters. We find two solutions in two horizons named as event and cosmological horizons by using the radial equation. We consider the intermediate regime and match these two solutions to obtain the greybody factor and examine its behavior graphically. It is found that the greybody factor has an inverse relation with the coupling constant, mass, charge as well as the radius of the black hole and has a direct relation with angular momentum.
