TL;DR: In this paper, the up-conversion emissions were measured using laser excitation at 978-nm, resulting in the following transitions: blue emission in the range of 450-500 nm, weak red emission in range of 650-680 nm and near infrared emission in a range of 765-840 nm for Tm3+, as well as green emission centered at 550-nm and weak near infrared emissions at 755-nm for the Ho3+ ions.

TL;DR: Endoclip is superior to both small and large volume injection of epinephrine in the prevention of recurrent bleeding in patients with peptic ulcer, whereas there were no differences in transfusion requirement or even 30 d mortality between the groups.

TL;DR: In this article, Eu 3+ :TiO 2 nanoparticles were used for temperature sensing in photoluminescence emission spectra, and the relative sensor sensitivity ranges from 0.17 to 2.43% −1 and is among the highest recorded for inorganic nanosensors.

TL;DR: Eu 3+, Sm 3+ and Tb 3+ ions have been incorporated into anatase TiO 2 nanocrystals via hydrolytic sol-gel method.

TL;DR: Eu( 3+)- and Dy(3+)-doped GdVO(4) samples synthesized by a high-temperature solid-state method are investigated by fluorescence spectroscopy and demonstrate potential for development as thermographic phosphors because the experimental and theoretical temperature dependence of the intensity ratio of the two lines agrees well.
