By using periodic functions from the nonnegative integers to the complex numbers, we generalize the generating function of the q-Apostol type Eulerian polynomials and numbers attached the character defined in . Then using this generating function, we a construct new L-type series. By using periodic functions, we derive decomposition of the generating functions for the q-Euler numbers and polynomials. Applying the Mellin transformation to the decomposition of the generating functions, we introduce and investigate the various properties of a certain new family of the Dirichlet type L-series and the Dirichlet L-function. Finally, we derive many potentially useful results involving these functions polynomials and numbers.
