  In this article, we study the propagation of scalar fields in the
gravitational background of a spherically symmetric, electrically charged,
regular-de Sitter black holes in higher dimensions. We carry out a thorough
investigation of the grey body factors, by deriving analytical expressions for
both minimally and non-minimally coupled scalar fields. Then we study the
profile of grey body factors in terms of particle properties, namely the
angular momentum quantum number and the non-minimal coupling constant, and the
spacetime properties, namely the dimension, the cosmological constant and the
non-linear charge parameter. We then derive the Hawking radiation spectra for a
higher-dimensional electrically charged regular-de Sitter black hole. We find
that the non-minimal coupling may suppress the greybody factor and the
non-linear charge parameter may enhance it, but they both suppress the energy
emission rate of Hawking radiation.
