Methylene blue loaded K_0.3Bi_0.7F_2.4:Yb,Er upconversion nanoparticles for near-infrared activated photodynamic therapy

Abstract

Bismuth-based fluoride nanoparticles have received a lot of interest as host material for upconversion, which have been recommended for lighting devices and biological applications. Bismuth is known as an ecofriendly...

A NaBiF4:Gd/Tb nanoscintillator for high-resolution X-ray imaging

“…However, the limited availability and high cost of rare earth compounds restricts the commercialization of these scintillator materials. 31–33 As a consequence, development of less expensive and non-rare earth and environmentally friendly host materials for scintillators is required urgently. Fortunately, elements like bismuth can substitute the rare earth element in NaREF 4 -based matrices with comparable performance.…”
