In this paper, we introduce the generalized Saitoh operator $L_{p}(a, c, eta)$ and using this operator, the new subclasses $mathcal{H}_{n,m}^{p, b}(a, c, eta),    mathcal{L}_{n,m}^{p, b}(a, c, eta ; mu), mathcal{H}_{n,m}^{p, b, lpha}(a, c, eta) $ and $mathcal{L}_{n,m}^{p, b,  alpha}(a, c, eta ; mu)    $ of the class of multivalent functions denoted by $mathcal{A}_p(n) $ are defined. Further for functions belonging to these classes, certain properties of neighborhoods are studied. ;
