NIST Atomic Spectra Database for Zn lines and their parameters you are looking for.

I didn't find these parameters in NIST data base that's why I am looking these in any other paper or so.

For stark broadening parameter for persistent lines of Zn-I and also transition time for 468 and 472 nm lines, I suggest two references:

1- Spectral Line Broadening by Plasmas: Hans R. Griem, Academic Press, University of Maryland, 1974 and

2- Plasma Spectroscopy b: Hans R. Griem, University ofMaryland,McGraw-Hill Book Comany, 1964.

 Unfortunately , I think that Griem did not calculated Stark parameters for Zn lines. In addition, determination of the line widths by using Voigt profile is not always appropriate.. see paper

N. Konjevic, 1999, Plasma broadening and shifting of non-hydrogenic spectral lines: present status and applications, Physics Reports 316, pp 339- 401.

In paper suggested by Reda Koramy, Stark broadening is negligible and generalization to your case may lead to significant error.  In fact, Stark profile of neutral lines is more complicated and described by j(A,R) function, see also Konjevic's paper. Only if ion broadening parameter A is small for your lines, Stark width can be determined by fitting with Voigt function. Even i that case using careful deconvolution procedure to separate it from other line broadening mechanism is necessary. 

  Unfortunately, transition probabilities for your lines are not determined also.,  see

http://physics.nist.gov/cgi-bin/ASD/lines1.pl

May be you have some other lines of some other elements which can be used for Ne determination?

 I suggest you, if not yet, to download papers:

Thank you very much for your derailed answer. I will try these papers but if i get life time of transition of any multiplet of Zn-I lines it would be of great importance for me. thank you

how i can get stark broadening parametrs for Yattrium-I?

Griem did not calculated it. Dimitrijevic and Sahal Brechot calculated only for Y II and Y III. I think that the only way is to contact Branimir Blagojevic to calculated it for you, according to semiclassical theory of Griem, see paper in Journal of Quantitative Spectroscopy & Radiative Transfer 217 (2018) 278–287. There are only data for He I, but he can perform calculations for other elements also.
