In this paper, we consider the following Schr & ouml;dinger-Poisson system -Delta u+u+Phi(y)u=Qn(y)|u|p-2u,y is an element of R3,-Delta Phi(y)=u2,y is an element of R3,\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\begin{aligned} {\left\{ \begin{array}{ll} -\Delta u+u+\Phi (y)u=Q_n(y)|u|<^>{p-2}u, \hspace{3mm}y \in {\mathbb {R}}<^>3,\\ -\Delta \Phi (y) =u<^>2, \hspace{3mm}y \in {\mathbb {R}}<^>3, \end{array}\right. } \end{aligned}$$\end{document}where p is an element of(4,6)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$p\in (4,6)$$\end{document} and Qn\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$Q_n$$\end{document} are concrete bounded functions whose self-focusing core supp{Qn+}\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$supp\{Q_n<^>+\}$$\end{document} shrinks to a finite set of points as n ->infinity\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$n\rightarrow \infty $$\end{document}.

We also prove the existence of localized bound state solutions for above Schr & ouml;dinger-Poisson system by using penalization method. Moreover, by using Green's representation formula, we improve the result in [14, Theorem 1.3] for nonlinear Schr & ouml;dinger equation.
