In the paper, we study a class of semilinear fractional semilinear elliptic equations involving concave-convex nonlinearities:
 $\begin{equation*} \left\{ \begin{array}{ll} (-\Delta)^{\alpha} u+V_{\lambda }\left( x\right) u = f\left( x\right) \left\vert u\right\vert ^{q-2}u+g\left( x\right) \left\vert u\right\vert ^{p-2}u & \text{in }\mathbb{R}^{N}, \\ u\in H^{\alpha}(\mathbb{R}^{N}), & \end{array}\right. \end{equation*}$
where
 $\alpha\in (0,1]$
,
 $1 2\alpha\right),$
the potential
 $V_{\lambda }(x) = \lambda a(x)-b(x)$
and the parameter
 $\lambda >0.$
Under some suitable assumptions on
 $a,b$
and the weight functions
 $f,g$
, we obtain the existence and multiplicity of non-trivial (positive) solutions for
 $\lambda$
large enough. An interesting phenomenon is that we do not need the condition that weight functions
 $f, g$
are integrable or bounded on whole space
 $\mathbb{R}^{N}.$
