how to add new ip scope in same vlan

You can't. A single VLAN has a single IP-scope.

But there are other options:

1. If it is possible in your addressing concept you could just change the subnet mask from for example /24 to /23. If your systems get the IP by DHCP, they will automatically adjust to the new mask and you are done.
2. Take this as a first step for some separation and build a new additional VLAN with a new IP-range.
