This paper deals with the asymptotic behavior of the solutions to a class of non-autonomous fractional stochastic \begin{document}$ p $\end{document} -Laplacian equation driven by linear additive noise on the entire space \begin{document}$ \mathbb{R}^n $\end{document} . We firstly prove the existence of a continuous non-autonomous cocycle for the equation as well as the uniform estimates of solutions. We then show pullback asymptotical compactness of solutions as well as the existence and uniqueness of tempered random attractors and the uniform tail-estimates of the solutions for large space variables when time is large enough to surmount the lack of compact Sobolev embeddings on unbounded domains. Finally, we establish the upper semi-continuity of the random attractors when noise intensity approaches zero.
