Evolution of Highly Biocompatible and Thermally Stable YVO₄:Er³⁺/Yb³⁺ Upconversion Mesoporous Hollow Nanospheriods as Drug Carriers for Therapeutic Applications.

ABSTRACT: In recent times, upconversion nanomaterials with mesoporous hollow structures have gained significant interest as a prospective nano-platform for cancer imaging and therapeutic applications. In this study, we report a highly biocompatible YVO₄:1Er³⁺/10Yb³⁺ upconversion mesoporous hollow nanospheriods (YVO₄:Er³⁺/Yb³⁺ UC-MHNSPs) by a facile and rapid self-sacrificing template method. The Rietveld analysis confirmed their pure phase of tetragonal zircon structure. Nitrogen adsorption-desorption isotherms revealed the mesoporous nature of these UC-MHNSPs and the surface area is found to be ~87.46 m²/g. Under near-infrared excitation (980 nm), YVO₄:Er³⁺/Yb³⁺ UC-MHNSPs showed interesting
