Microstructure and Raman spectra of Ag-MgF2 cermet films

Ag-MgF_(2) cermet films with different Ag fractions were prepared by vacuum evaporation. The microstructure of the films was examined by Raman scattering technique. The surface-enhanced Raman spectrum for MgF_(2) molecules in the cermet film strongly suggests the existence of Ag nanoparticles dispersed in MgF_(2) matrix. The intensities of the Raman spectra of Ag-MgF_(2) cermet films increase with Ag fraction. The enhancement of Raman scattering disappears when Ag content reaches wt.20%. The ana

This warning message is typically encountered in C or C++ when a non-void function does not have a return statement at the end of the function. In C and C++, non-void functions must have a return statement that returns a value of the function's return type. If a non-void function does not have a return statement, or if the return statement is missing a value, the compiler will issue a warning. The warning message "reaches end of non-void function" specifically indicates that the function has reached the end of its code without encountering a return statement. This can occur in situations where the programmer has forgotten to include a return statement or has accidentally left it out. To resolve this warning, the programmer should ensure that all non-void functions have a return statement that returns a value of the correct return type.
