Claim 0:
1. A substrate comprising:
a base substrate comprising bowl-curved-shaped nanodimples and spiked nanotips formed at contact points between the bowl-curved-shaped nanodimples; and
a plasmonic continuous film with a curved surface formed on the base substrate, the curved surface comprising plasmonic nanodimples formed over the bowl-curved-shaped nanodimples,
wherein a depth-to-radius ratio of each of the plasmonic nanodimples formed of the plasmonic continuous film is 1.5 or above,
wherein inclination angles of side surfaces of each of the bowl-curved-shaped nanodimples are in a range from 30 to 60 degrees.
