Abstract Hawking radiation of Klein--Gordon and Dirac particles in a non-stationary Kerr--Newman--de-Sitter black hole is studied by introducing a new tortoise coordinate transformation. The result shows that the Fermi--Dirac radiant spectrum displays a new term that represents the interaction between the spin of spinor particles and the rotation of black holes, which is absent in the Bose--Einstein distribution of Klein--Gordon particles.
