This paper concerns the following nonlinear Choquard equation:
$ \begin{equation} -\varepsilon^{2}\Delta w+V(x)w = \varepsilon^{-\theta}W(x)(I_\theta*(W|w|^p))|w|^{p-2}w,\quad x\in\mathbb{R}^N, ~~~~~~~~~~~~(*)\end{equation} $
where
$ \varepsilon>0,\ N>2,\ I_\theta $
 is the Riesz potential with order
$ \theta\in(0,N),\ p\in\big[2,\frac{N+\theta}{N-2}\big),\ \min V>0 $
 and
$ \inf W>0 $
. Under proper assumptions, we explore the existence, concentration, convergence and decay estimate of semiclassical solutions for
$ (\ast) $
. The multiplicity of solutions is established via pseudo-index theory. The existence of sign-changing solutions is achieved by minimizing the energy on Nehari nodal set.
Keywords: Choquard equation, Riesz potential, pseudo-index, nodal solution, concentration.
