I looked at DIAMETER interfaces and went on Dz interface. It is an interface between BSF and SLF. For SLF i was aware of like Subscriber Location Function but BSF i didn't even have a hint.
is here anyone who can explain this?

The BSF queries SLF over Dz as you mentioned to get the name of the HSS containing the required subscriber specific data.

It's similar to Zh or Zh' (Z-h-prim) interface used by BSF to connect to HLR to fetch authentication information.

Check the 3GPP 33.220 for more details

BSF is hosted in a network element under the control of an Mobile Network Operator (MNO).

BSF, HSS and UE participate in Generic Bootstraping Architecture (GBA) in which a shared secret is established between the network and a UE by running the bootstrapping procedure. The shared secret can be used between Network Application Functions (NAF's) and UE's,
E.g. : For authentication purposes

For Specification TS 33.220
