In this study, we aim to compare the changes in the luminescence properties of Ga2O3:Cr3+ modified by Al or Sc ion substitution (chemical pressure) and hydrostatic pressure. We find the same behavior for Ga2–x Al x O3:Cr3+ and different behavior for Ga2–x Sc x O3:Cr3+ in terms of the optical properties under chemical and mechanical pressure. We consider Al substitution, which does not affect the chemical bond angles in the Cr3+ local environment and changes the crystal volume, like mechanical pressure does. As confirmed by Raman spectroscopy, the Sc ions cause lattice distortion and influence the chemical bond lengths and angles in the Cr3+ local environment. The energy structure diagrams of all levels of the d3 configuration of the Cr3+ ion as a function of pressure are calculated by considering the pressure dependence of the Racah parameters. The energy structure diagrams presented in the paper show a decrease in the energy of the 2E, 2T1, and 2T2 excited levels with an increase in Dq. This does not align with the behavior predicted for these excited levels by the standard Tanabe–Sugano diagram. It seems correct that a high-pressure experiment involving Cr3+ and other transition metals should be interpreted using the method and diagrams presented herein.

“…The remote pressure measurements offered by luminescent manometer phosphors are crucial for enabling the technology of numerous new diagnostic fields, which were unavailable to any previous pressure-monitoring techniques. − The use of a pressure-dependent luminescence band shift, changes in luminescence kinetics, or the ratio of the intensity of two luminophore emission bands do not require electrical connections between the sensor and the sensing system. ,, This is especially important in a pressure chamber of the diamond anvil cell (DAC), microfluidic systems, or even biological systems. − One of the most popular and widely used luminescent pressure indicators is ruby, Al 2 O 3 :Cr 3+ . In this case, an increase in pressure leads to an increase in the covalence of the Cr 3+ –O 2– bond and a decrease in the Racah parameter.…”

Luminescence manometry is most often realized by a spectral shift of luminescence bands. Typically, the shift of spectrally narrow-band emission is quantified, which is highly precise but not very sensitive to pressure variations. Alternatively, the spectral shift of a broadband emission may be exploited, which is more sensitive but less precise, due to the difficulty in accurate determination of the band centroid. In this work, a mixed approach is presented, combining the shift in broadband chromium emission from the 4T2 → 4A2 level with a narrow-band neodymium emission (4F3/2 → 4I11/2 transition), observed in the La3Ga5GeO14 spectrum. The resulting optical Nd3+-based manometer demonstrates an absolute sensitivity of 2.92 cm–1/GPa for the 4F3/2 → 4I11/2 electronic transition. An additional advantage of using this material is its negligible spectral shift with temperature, determined in the T range of 77–343 K, making the pressure readouts independent of this parameter (i.e., temperature variations).

“…12,13 Moreover, despite the fact that f-d transition centers can achieve high sensitivity in pressure sensing, their reliability is often compromised by the broad emission features of f-d transitions in practical measurements. 14 Compared with rare-earth luminescent centers, Mn 4+ , as a type of transition metal ion, are earth-abundant and relatively inexpensive. Using them as luminescent centers only requires a simple high-temperature solid-state synthesis in air.…”

Multifunctional phosphors have significant application and scientific value and are becoming a research hotspot in the field of luminescent materials. Herein, we report Mn 4+ -activated double-perovskite-type Sr 2 LuNbO 6 multifunctional phosphors with excellent comprehensive properties in the fields of optical temperature/pressure sensing and w-LED lighting. The crystalline structure, elemental composition, optimal doping concentration, crystal-field strength, and optical bandgap of the phosphors are investigated in detail, and the mechanisms of concentration and thermal quenching are discussed. From the optimal Sr 2 LuNb 0.998 O 6 :0.2%Mn 4+ phosphor, a LED lamp for indoor warm-white lighting is successfully fabricated. Further, the thermometric properties of the phosphors are explored for applications as FIR-and lifetime-based thermometers, showing a maximum relative sensitivity of 1.55% K −1 at 519 K. Upon pressure loading, a significant red-shift of the peak centroid is observed, and the pressure sensitivity is determined to be 0.82 nm/ GPa. These results suggest that the Mn 4+ -activated Sr 2 LuNbO 6 multifunctional phosphors have great potential to be utilized in the fields of optical thermometry, manometry, and lighting.
