Doping an ionic compound

Before I begin my next experiment, I was hoping to get some feedback in regards to it.

What I was thinking of doing was growing a crystal of sodium chloride, doped with copper. I have chosen sodium chloride as the host mostly because it is the easiest pure compound I can produce with what I have on hand (my shelf of chemicals includes both hydrochloric acid and sodium hydroxide). My selection of copper as a dopant is for a similar reason: I have more powdered copper than I know what to do with.

My concern is in regards to doping the NaCl crystal with copper. To get ions of copper into the aqueous solution of sodium chloride, I am thinking it would be best to dissolve some copper dichloride into it.

Should that work? Or, am I going to be looking at a crystal of CuCl2, with some little bits of NaCl mixed in? Or perhaps, copper dichloride doped with sodium?

I would appreciate any thoughts you guys might have.
