“…227–229 High pressure on the order of GPa in the DAC is determined by measuring the PL shift of a pressure-sensing luminescent material with increasing pressure. 230 A representative material is a ruby (Cr 3+ -doped Al 2 O 3 ), the sharp emission peak (R 1 -line) of which is observed at 694 nm under ambient pressure and red-shifted under high-pressure conditions. 231–235 Since the wavelength shift is only about 4 nm, even under 10 GPa, a photodetecting system with relatively high spectral resolution is required.…”

“…There are many reports about new pressure-sensing phosphors activated with not only Cr 3+ but also Mn 2+ , Eu 2+ , Sm 2+ , and Sm 3+ . 230,236–243 These phosphors, including ruby, exhibit a nearly linear PL wavelength shift Δ λ with respect to pressure; the P – λ dependence can be described by a simple linear function. Under 20 GPa, the pressure sensors of ruby, Y 3 Al 5 O 12 :Sm 3+ , and SrB 4 O 7 :Sm 2+ show PL shifts of 0.365 nm GPa −1 , 232 0.306 nm GPa −1 , 241 and 0.255 nm GPa −1 , 242 respectively.…”

Nanomechanical resonators made of suspended graphene exhibit high sensitivity to pressure changes. Nevertheless, the graphene resonator pressure performance is affected owing to the gas permeation problem between the graphene film and the substrate. Therefore, we prepared edge-deposited graphene resonators by focused ion beam (FIB) deposition of SiO 2 , and their gas leakage velocities and pressure-sensing ability were demonstrated. In this paper, we characterize the pressure-sensing response and gas leakage velocities of graphene membranes using an all-optical actuation system. The gas leakage velocities of graphene resonators with diameters of 10, 20, and 40 μm are reduced by 5.0 × 10 6 , 2.0 × 10 7 , and 8.1 × 10 7 atoms/s, respectively, which demonstrates that the edge deposition structure can reduce the gas leakage of the resonator. Furthermore, the pressure-sensing performance of three graphene resonators with different diameters was evaluated, and their average pressure sensitivities were calculated to be 3.4, 2.4, and 1.9 kHz/ kPa, with the largest full-range hysteresis errors of 0.6, 0.7, and 1.0%, respectively. The temperature stabilities of the three sizes of resonators in the temperature range of 300−400 K are 0.016, 0.015, and 0.016%/K, and the maximum resonance frequency drift over 1 h is 0.0058, 0.0048, and 0.0112%, respectively. This work has great significance for the improvement of gas leakage velocity characterization of graphene membrane and graphene resonant pressure sensor performance optimization.

“…The utilization of Cr 3+ -activated optical materials, which exhibit efficient emission within the visible and near-infrared (NIR) spectrum, has garnered significant interest due to emerging demands in fields such as biological imaging, freshness analysis, luminescence thermometry and luminescence manometry exploiting their NIR luminescence capabilities. − Particularly, these materials have found practical application in NIR phosphor-converted light-emitting diodes (pc-LEDs), representing a new frontier in NIR light sources owing to their cost-effectiveness, superior efficiency, and compact form factor poised to replace conventional tungsten halogen lamps . The pc-LEDs leverage high-power blue LED chips combined with inorganic phosphors to achieve targeted NIR emissions.…”

In this study, we synthesized a series of Ga 1.98−x In x O 3 :0.02Cr 3+ materials with varying x values from 0.0 to 1.0, focusing on their broadband near-infrared emission and photoelectric properties. Interestingly, photocurrent excitation spectra exhibited behavior consistent with the absorption spectra, indicating the promotion of carriers into the band structure by the 4 T 1 , and 4 T 2 states of Cr 3+ ions. This association suggests that photocurrent in this material is influenced not only by valence to conduction band transitions but also by transitions involving Cr 3+ dopants. Our investigation of luminescence quenching mechanisms revealed that nonradiative processes were not directly linked to thermally induced relaxation from the excited state 4 T 2 to the ground state 4 A 2 , as usually suggested in the literature for this type of material. Instead, we linked it to the thermal ionization of Cr 3+ ions. Unexpectedly, this process is unrelated to the transfer of electrons from Cr 3+ impurities to the conduction band but is associated with the formation of holes in the valence band. This study provided novel evidence of luminescence quenching via the hole-type thermal quenching process in Cr 3+ -doped oxides, suggesting potential applicability to other transition metal ions and host materials. Finally, we demonstrated the dual-purpose nature of Ga 1.98−x In x O 3 :0.02Cr 3+ as a practical emitter for NIR-pc-LEDs and effective photocurrent for UV detectors. This versatility underscores these materials' practicality and broad application potential in optoelectronic devices designed for near-infrared and ultraviolet applications.
