have you guys tried using ULN2803 as driver for 74LS595 for use in LED matrix
thanks...

I don't see any problem in doing that!

It's no question, if a 74LS595 (or any other 5V digital logic) can drive an ULN2803. You'll find thousands of circuit examples. There may be rather problems to dimension the current and duty cycle for a LED matrix. But you didn't ask, thus I assume, you know about.

I use in my design ULN2003A . ULN2803A is similar ( octal high voltage , high current darlington arreys).
