Synthesizing Ag⁺: MgS, Ag⁺: Nb₂S₅, Sm³⁺: Y₂S₃, Sm³⁺:Er₂S₃, and Sm³⁺:ZrS₂ Compound Nanoparticles for Multicolor Fluorescence Imaging of Biotissues.

ABSTRACT: Development of the fluorophores whose fluorescence bands can be flexibly selected is of great interest for biotissue imaging. Compounds of Ag⁺:MgS, Ag⁺:Nb₂S₅, Sm³⁺:Y₂S₃, Sm³⁺:Er₂S₃, and Sm³⁺:ZrS₂ were obtained through new chemical synthesis. They were characterized by X-ray photoelectron spectroscopy, X-ray diffraction spectroscopy, and transmission electron microscopy. They revealed polychromatic-photoluminescence spectra when excited by 280, 380, 480, 580, 680, and 785 nm light. Especially, near-infrared emission ranging from 800-1100 nm was found upon 785 nm light excitation. A band model was proposed to explain transitions responsible for the observed comp
