Zeros of Ramanujan Type Entire Functions

In this work we establish some polynomials and entire functions have only real zeros. These polynomials generalize q-Laguerre polynomials $L_n^{(\alpha )}(x;q)$, while the entire functions are generalizations of Ramanujan’s entire function $A_q(z)$, q-Bessel functions $J_{\nu }^{(2)}(z;q)$, $J_{\nu }^{(3)}(z;q)$ and confluent basic hypergeometric series.
