How can I make my wife to put down the phone in bed? She keeps working til late and I can’t sleep.

There’s really not much you can do besides communicate to her how her behavior makes you feel, why it makes you feel that way, and how it could change. Otherwise investing in a sleep mask might be a good idea!

You’ve got a couple of options here. Either ask her to not work in bed or try sleeping with earplugs and and sleep mask.
