The development of current technology imposes more and more requirements for
measurement techniques, where one of the most important is temperature measurement. In …

Temperature is important because it has an effect on even the tiniest elements of daily life
and is involved in a broad spectrum of human activities. That is why it is the most commonly …

Below the Earth's crust, temperatures may reach beyond 600 K, impeding the batteries used
to power conventional thermometers. Fluorescence intensity ratio based temperature probes …

A ratiometric optical thermometer based on triply‐doped La2O3: Yb3+/Er3+/Nd3+
microcrystals is reported with a relative sensitivity above 1% K− 1 in the entire range from …

Here, we report the synthesis of Eu: ZnO nanorods by a hydrothermal method and their use
as fluorescence intensity ratio (FIR) based optical temperature sensors. The as-prepared …

Abstract Dy 3+-and Nd 3+-doped YNbO 4 powders were prepared using a
mechanochemical method followed by annealing, and their photoluminescent properties …

Traditional applications of the Judd-Ofelt (JO) theory to the analysis of the Eu 3+ optical
spectra make use of the emission transitions originating from the 5 D 0 manifold. In the …

By studying the temperature-induced red-shift of the Vsingle bondO charge transfer band
(CTB) edge in YVO 4: 10% Eu 3+, we demonstrate a high-sensitive strategy for optical …

Eu3+ and Er3+ co-doped YNbO4 powder phosphors were synthesized by a traditional high-
temperature solid-state reaction method. A laser of 487.6 nm wavelength was selected to be …

Luminescence thermometry on europium doped TiO 2 films, prepared by the plasma
electrolytic oxidation, was investigated by the Luminescence Intensity Ratio method. The …
