To shift the onset of thermal quenching by multiphonon emission to higher temperatures,
thermographic phosphors for high-temperature applications are usually selected with a …

Rare-earth ions (REIs) have incomplete 4f shells and possess narrow optical intra-4f
transitions due to shielding from electrons in the 5s and 5p orbitals, making them good …

Aiming to accomplish synchronous optical temperature measurements in the first, second,
and third biological windows, this work has carefully designed a novel ratiometric optical …

Er3+ ion doped eye-safe lasers operating at a wavelength of 1.5 μm have attracted attention
for use in many applications requiring protection from accidental retina exposure. For eye …

The temperature dependences of 1.53 μm near infrared and green upconversion (UC)
emissions of Er 3+ ion have been investigated in Er 3+/Yb 3+: BaMoO 4 powders upon 980 …

The influence of temperature on the near-infrared emission band corresponding to the
radiative relaxation from 4 I 13/2 to 4 I 15/2 electronic states of Er 3+ was investigated in Y 2 …

We describe a methodology to synthesize trivalent-erbium (Er3+)-doped yttrium oxide
(Y2O3) nanoparticles. An in-depth morphology analysis indicates that the average diameter …

Erbium-doped materials have been investigated for generating and amplifying light in low-
power chip-scale optical networks on silicon, but several effects limit their performance in …

It is important to explore luminescent single-molecule magnets (SMMs) to promote their
application in high-density data storage. Herein, we report two dimetallofullerenes of DyEr …

The ultraviolet (uv) absorption spectra, representing transitions to all energy levels below 44
500 cm− 1 of trivalent erbium (Er 3+)⁠, have been analyzed for the crystal-field splitting of …
