Ultrapure single-band red upconversion luminescence in Er doped sensitizer-rich ytterbium oxide transparent ceramics for solid-state lighting and temperature sensing.

Achieving single-band upconversion (UC) is a challenging but rewarding approach to attain optimal performance in diverse applications. In this paper, we successfully achieved single-band red UC luminescence in YbO: Er transparent ceramics (TCs) through the utilization of a sensitizer-rich design. The YbO host, which has a maximum host lattice occupancy by Yb sensitizers, facilitates the utilization of excitation light and enhances energy transfer to activators, resulting in improved UC luminescence.

C-reactive protein-to-albumin ratio is a predictor of hepatitis B virus related decompensated cirrhosis: time-dependent receiver operating characteristics and decision curve analysis.

Background And Aims: Hepatitis B virus (HBV) infection remains a major health problem and HBV-related-decompensated cirrhosis (HBV-DC) usually leads to a poor prognosis. Our aim was to determine the utility of inflammatory biomarkers in predicting mortality of HBV-DC.

Materials And Methods: A total of 329 HBV-DC patients were enrolled.
