Fluorescence intensity ratios (FIRs) of the 640nm and 602nm emissions from Sm3+ were recorded at various temperatures T to identify the temperature increases T associated with laser-induced local heating of Ag nanoparticles. The FIRs increased as intensities of the excitation beam from a 532-nm continuous-wave laser increased. Estimated T of the irradiated region increased to as high as 586 degrees C when at laser irradiation of 1.5W on the surface containing Ag nanoparticles. Local heating due to the surface plasmon resonance of Ag nanoparticles is a main reason for the T that eventually leads to precipitation of PbS quantum dots in glasses.
