The Extracorporeal Life Support Organization (ELSO) was formed in 1989 as a group of centers that were actively using extracorporeal life support (ECLS) the management cardiopulmonary failure. Among functions ELSO are enhancing communication, developing guidelines for ECLS, and maintaining registry ECLS cases. In 2021, had 543 domestic international who report data to registry.[1]

In this study, LaF3–LaOF:Yb3+/Ho3+ upconversion (UC) phosphors were synthesized via a solid-state reaction and their optical properties analyzed. The analysis of photoluminescence (PL) characteristics revealed strong emission at wavelength 543 nm for molar ratios La:Yb:Ho = 1:x:y, where x 0.04–−0.06 y 0.01–−0.03. pump power dependence phosphor PL the fluorescence lifetime then measured, mechani...
