作者： Chong Ji y. Jan Kalimullah Stroke Center New York Medical College Westchester Medical Center Valhalla NY USA Neurovascular Fellow New York Medical College Westchester Medical Center Valhalla NY USA

Rivaroxaban, a direct oral anticoagulant, has proven efficacy.and safety.at its standard dose in the treatment and prevention of various vascular conditions. These include the treatment of venous thromboembolism and stroke prevention in non-valvular atrial fibrillation. A "very.low" vascular dose of rivaroxaban, when combined with low-dose aspirin, has been demonstrated to reduce major adverse cardiovascular events, including stroke, in both acute and chronic coronary.sy.drome. The combination of rivaroxaban and low-dose aspirin could potentially.offer an additional strategy.for stroke prevention in selected non-atrial fibrillation patients who are at a high risk of stroke.

We investigated the emission properties of Eu3.-doped GdNbO4-based oxide phosphors,aiming at improving the Eu3.emission by.codoping of Bi3.and Li+.Eu3.singly.doped,Eu3.and Bi3.doubly.doped,and Eu3.,Bi3.,and Li+triply.doped GdNbO4were prepared using a high-temperature solid-state reaction *** red-orange emissions from Eu3.in the singly.doped samples are significantly.improved by.the codoping of Bi3.,mainly.due to the energy.transfer from Bi3.to Eu3..The additional codoping of Li+is found to increase the Eu3.emission *** improvement might be attributed to the increase in the photoluminescent quantum y.eld originating from larger grain sizes and better cry.tallinity.A detailed analy.is of the X-ray.diffraction pattern and the asy.metric ratio estimated from the photoluminescence spectra show that the local lattice environment around Eu3.in GdNbO4does not change significantly.with the codoping of Bi3.and Li+.Our results indicate that Li+doping is a promising way.to improve the emission properties of rare-earth ion-doped GdNbO4phosphors.
