“…Also, the point where the decrease in the intensity of the 3 P 0 level transition intersects with the increase in the intensity of the 1 D 2 transition shifts toward higher temperatures as the grain size increases. This phenomenon has been reported to be related to the ratio of the surface to volume ion ratio and participation of the “superficial” ions in electron–phonon interactions . Recently, Bolek et al have shown that by engineering the band gap by varying the ratio of Ga to Al in garnets, it is possible to control the thermometric properties of these materials.…”

“…In Gd 2.97 Pr 0.03 Ga 3 Al 2 O 12 , several transitions can be used to calculate temperature dependencies, but from the application point of view, it is the most important to find the transition with the highest sensitivity as well as with the widest temperature range where this dependance is linear. The sensitivity based on the luminescence intensity ratio, S r , and can be expressed as where LIR is the luminescence intensity ratio of particular transitions …”

In order to obtain Gd 2.97 Pr 0.03 Ga 3 Al 2 O 12 powders with different crystallite sizes, a modified Pechini (sol−gel) method was used. Powders were then used for the preparation of ceramics by a high-pressure low-temperature sintering method. The impact of crystallite size and pressure applied during the sintering procedure on conventional and persistent luminescence was investigated and analyzed. It was found that the emission color is strictly dependent on the crystallite size, as such phenomenon may be used in the field of advanced anti-counterfeiting. The spectroscopic properties of Gd 2.97 Pr 0.03 Ga 3 Al 2 O 12 were characterized by means of photoluminescence measurements. The kinetics of luminescence were measured in order to analyze the energy transfer between 3 P 0 and 1 D 2 excited states that also take an active role in the persistent luminescence process. It was found that an increase in the crystallite size led to a higher energy transfer from the 3 P 0 to 1 D 2 level and a change in the emission color. As such, it was studied for potential application in ratiometric optical thermometry. The effect was also investigated in terms of persistent luminescence. It was also found that the sintering pressure causes changes in the crystallographic parameters of the powders and, in consequence, has a great impact on the optical properties of ceramics. The conducted research gives insights into the mechanism of persistent luminescence and expands the application field of optical storage materials.

Despite the remarkable luminescent properties and temperature sensing capabilities of lanthanide materials, their photothermal effect in practical temperature measurement systems presents a major challenge to sensing reliability. Herein, taking Pr3+ as a typical exemplar, the influence of excitation wavelength and excitation approach on temperature sensing is systematically examined. The pulsed laser excitation method is identified as an efficient tactic to restrain the self‐heating of luminescence materials. In accordance with this principle, it is discovered that diverse excitation wavelengths give rise to alterations in the internal energy transport channels and further impact the temperature sensing performance. The 980 nm pulsed laser can result in the non‐thermal coupling occupying states of 3P0/3P1, which are recognized as thermal coupling energy levels in the conventional concept, and yield a relative sensitivity (Sr) performance more than three times superior to that of down‐shifting‐based sensing. The work provides a comprehensive analytical solution for achieving highly sensitive and stable temperature sensing based on excitation wavelength and working mode strategies.
