The melting points of Au@Ag CSNPs with different sizes. (a) The green arrows show that the melting points increase as the shell-size increases with a fixed core size for all the NPs. (b) The dotted lines show that the melting points increase as the core size increases with a fixed shell thickness for all the NPs except for the Au 2 @Ag 2 CSNP.
