Doping induced stable room temperature dual emission from gadolinium doped vacancy ordered double halide perovskite, Gd:Cs2SnCl6
The recent advancement in bandgap engineering through controlled doping has widen the prospectof vacancy ordered double halide perovskites (VO DHPs) by conferring them with designableoptoelectronic properties. Here, we report synthesis of Gd doped Cs2SnCl6 via a simplesolvothermal method. Gd3+ ions doping lowers the band gap from 3.8 eV to 2.8 eV and facilitatesstable room temperature dual PL emission centered at 440 nm and 610 nm. The macroscopicemission process is well supported by the confocal PL emission studies on isolated crystallites.Both the pristine (Cs2SnCl6) and Gd:Cs2SnCl6 exhibit crystalline cubic structure with Fm3m spacegroup. Rietveld refinement correlates well with the cubi…
Intubation Practices and Adverse Peri-intubation Events in Critically Ill Patients From 29 Countries
Importance: Tracheal intubation is one of the most commonly performed and high-risk interventions in critically ill patients. Limited information is available on adverse peri-intubation events. Objective: To evaluate the incidence and nature of adverse peri-intubation events and to assess current practice of intubation in critically ill patients. Design, Setting, and Participants: The International Observational Study to Understand the Impact and Best Practices of Airway Management in Critically Ill Patients (INTUBE) study was an international, multicenter, prospective cohort study involving consecutive critically ill patients undergoing tracheal intubation in the intensive care units (ICUs…
