  We prove resolvent estimates in the Euclidean setting for Schr\"{o}dinger
operators with potentials in Lebesgue spaces: $-\Delta+V$. The $(L^{2}, L^{p})$
estimates were already obtained by Blair-Sire-Sogge, but we extend their result
to other $(L^{p}, L^{q})$ estimates using their idea and the result and method
of Kwon-Lee on non-uniform resolvent estimates in the Euclidean space.
