The energy-emission rate is analyzed for different parameter choices in HSW void spacetimes with a quintessential field. In the left panel, δ_c is varied while keeping γ = 0.1 and ρ_s = 0.1 fixed. The middle panel highlights the impact of varying γ with δ_c = 0.1 and ρ_s = 0.1, while the right panel illustrates the influence of ρ_s on f(r) with δ_c = 0.1 and γ = 0.1.
