Summary: We consider Toeplitz operators $T_a^{(\lambda)}$ acting on the weighted Bergman spaces $\Aa_\lambda^2(\Pi)$, $\lambda \in [0,\infty)$, over the upper half-plane $\Pi,$ whose symbols depend on $y=\im z$. Motivated by the Berezin quantization procedure we study the dependence of the properties of such operators on the weight $\lambda$ and, in particular, under the limit procedure $\lambda\rightarrow\infty$.

Keywords: Weighted Bergman spaces, Toeplitz operator, boundedness, spectrum
