“…This phenomenon might be ascribed to a new matching relationship of the average effective ionic radius between the [Lu/YO 8 ] and [Al/ScO 6 ] sites was established, and higher structural rigidity of the host was obtained [35,36]. The above results demonstrated that prepared LuYScCr NIR-PCs presented superior thermal stability compared with that the reported garnet NIR phosphors, such as Y 3 Ga 3 MgSiO 12 :Cr 3+ (~20%) [16], Ca 2 LuScAl 2 Si 2 O 12 :Cr 3+ (~24%) [17], Gd 2.4 Lu 0.6 Ga 4 AlO 12 :Cr 3+ (~25%) [18], and LiInSi 2 O 6 :Cr 3+ (~23%) [55].…”

Near-infrared (NIR) phosphor-converted light-emitting diodes/laser diodes (LEDs/LDs) are prospective lighting sources for NIR spectroscopy. However, developing NIR phosphor materials with desired thermal robustness and high photoelectric efficiency is a crucial challenge for their applications. In this work, based on the cationic radius matching effect, a series of (Lu,Y) 3 (Al,Sc,Cr) 2 Al 3 O 12 NIR phosphor ceramics (LuYScCr NIR-PCs) were fabricated by vacuum sintering. Excellent thermal stability (95%@150 ℃) was obtained in the prepared NIR-PCs, owing to their weak electron-phonon coupling effect (small Huang-Rhys factor). Being excited at 460 nm, NIR-PCs realized a broadband emission (650-850 nm) with internal quantum efficiency (IQE) of 60.68%. Combining NIR-PCs with LED/LD chips, the maximum output power of the encapsulated LED prototype was 447 mW@300 mA with photoelectric efficiency of as high as 18.6 %@180 mA, and the maximum output power of the LD prototype was 814 mW@2.5 A. The working temperatures of NIR-PCs were 70.8 ℃@300 mA (LED) and 102.8 ℃@3 A (LD). Finally, the prepared NIR-PCs applied in food detection were verified in this study, demonstrating their anticipated application prospects in the future.

Constructing a phosphor with multifunctional applications is an imperative challenge. Especially, highly thermostable luminescence of phosphor is indispensable for stable whitelight-emitting diodes (LEDs). Nevertheless, good thermal quenching resistance behavior is unfavorable for a fluorescence intensity ratio (FIR)-based optical temperature sensor. Herein, a highly thermostable Ba 3 (ZnB 5 O 10 )PO 4 (BZBP)-based phosphor is successfully achieved via replacing Ba 2+ with Dy 3+ , demonstrating simultaneously promising lighting and thermometry utilizations. Under the excitation of 350 nm, the title phosphor only loses 12% of the initial intensity when the temperature is up to 473 K, ensuring sufficient luminescence thermostability for white-LED lighting. The white-LED device fabricated using the title phosphor emits highquality white light with a high color rendering index (R a = 93) and low correlated color temperature (CCT = 3996 K). Meanwhile, the yellow and blue emission intensities demonstrate a downtrend difference with rising temperature. Temperature sensing properties are assessed through FIR technology. The maximal relative sensitivity reaches as high as 0.0379 K −1 at 298 K. These results reveal that the title phosphor has a great potential for indoor lighting and thermometry applications.

“…The repeatability ( R ) of the sample must be assessed to establish if the crystals are an effective thermal probe. The following equation may be used to determine this parameter: 69 where M i ( T ) c is the measured parameter (FIR or band centroid) in the i th cycle and M ( T ) c is the mean value of the M ( T ) c over 10 cycles. The FIR measurement was performed five times in a succession without altering the experimental equipment.…”
