“…39–42 For example, NaGdF 4 :Nd 3+ ,Yb 3+ , and Cr 3+ nanoparticles were used as nanoscale photothermal agents and luminescence thermometers. 43 Low-dose X-ray-stimulated LaGaO 3 :Sb,Cr near-infrared persistent luminescence nanoparticles were designed for in vivo whole-body and renewable bioimaging. 44 These nanoscale compounds have a risk of accumulation in the body.…”

“…[33][34][35][36][37] By controlling the ET between Cr 3+ and Yb 3+ , continuous coverage of the NIR spectrum in the range of 700-1100 nm can be achieved, and the luminescence properties of materials can also be effectively improved. [11,[37][38][39][40][41][42] However, the Cr 3+ -Yb 3+ co-doped phosphors can only cover the NIR-I region due to the limited spectral properties of Cr 3+ -Yb 3+ . The emission spectrum of Ni 2+ ions is in the NIR-II region, and recently researchers have realized NIR phosphors covering the NIR-I and NIR-II regions through a Cr 3+ -Ni 2+ ET strategy.…”

To realize efficient and broadband near infrared (NIR) light in both NIR‐I and NIR‐II regions, Gd3Mg0.5Al1.5Ga2.5Ge0.5O12 (GMAGG): Cr3+, Yb3+, Ni2+ phosphors are prepared in this study. The effects of Cr3+‐Yb3+ co‐doping and Cr3+‐Yb3+‐Ni2+ tri‐doping on the luminescence properties are investigated. GMAGG: Cr3+, Yb3+ exhibits high internal quantum efficiency (IQE) of 96.4%, and near‐zero thermal quenching (96.5%@423 K) in 650–1100 nm. By constructing energy transfer from Cr3+ to Ni2+, the emission range of GMAGG: Cr3+, Yb3+, Ni2+ is further extended to 650–1700 nm with a high IQE of 28% and good thermal stability (66%@423 K). The NIR LEDs prepared with GMAGG: 0.04Cr3+, 0.008Yb3+, and GMAGG: 0.04Cr3+, 0.008Yb3+, 0.04Ni2+ exhibit 57.5 and 8.1 mW at an input current of 100 mA, respectively. The results show that GMAGG: Cr3+, Yb3+, Ni2+ is a promising NIR phosphor for NIR light sources.

The skillful combination of luminescent thermometry and optical heating has enabled the development of luminescent optical density meters. However, developing such sensing materials with predefined sensing performance requires an understanding of which material parameters play a dominant role in the optical response of the system. In this study, a systematic investigation is conducted on the influence of host material composition and crystal field strength affecting the Cr3+ ions on the sensing performance of the ratiometric optical density meter based on the 2E→4A2 to 4T2→4A2 luminescence intensity ratio (LIR) in Y3Al5‐xGaxO12:Cr3+. As shown, the LIR reveals thermal variation according to the Boltzmann distribution in these materials over the 160 to 500 K range. However, at higher temperatures, monotonic changes in LIR are still observed. This has enabled the development of optical density meters with high sensitivity, operating over a wide range of power densities (<5500 W cm−2). The maximum sensitivity is found for Y3Al3Ga2O12:Cr3+, reaching 0.086% W−1 cm2 at 2 W cm−2, which is the highest value reported to date among all ratiometric Cr3+‐based optical density meters. It is demonstrated that a strong crystal field favorably influences the thermal sensitivity of the analyzed systems, thereby achieving high sensitivity in the low optical power density range (<1000 W cm−2). However, it also limits the operating range of the sensing material. Conversely, to extend the operating range of the optical density meter, materials with intermediate or low crystal field strengths are preferred.
