In this paper, we study the computational modeling of the localized surface plasmonic and scattering field effect arising from of gold nanorods. We also report the synthesis and optical characterization of core-spacer-shell nanocomposites composed of
Nanoparticles doped with rare earth ions for biomedical imaging and infrared photodynamic therapy (IRPDT) have been synthesized, characterized, and compared. Specifically, these nanoparticles utilize two primary modalities: near infrared excitation a
