Emission characteristics of thin film contained RhB and gold nanoparticles of different shapes. For each film spectra were recorded with different laser powers, a PVP RhB emission spectrum c Au@AgNRs showed the spectral narrowing behavior at 1.2 mJ e. AuNRs @ 400 μJ and g. AuNPs showing spectral property at high power 5.3 mJ. The corresponding figures b, d, f and h are showing the intensity vs. FWHM of the emission spectrum with varying pump powers
