Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

open access: yesAdvanced Materials, Volume 37, Issue 39, October 2, 2025.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

Noninvasive Assessment Methods for the Therapeutic Effect Following Facial Rejuvenation

open access: yesJournal of Cosmetic Dermatology, Volume 24, Issue 10, October 2025.
ABSTRACT Background As the demand for facial rejuvenation continues to rise, monitoring the response to therapy is worthy of attention. However, a standardized system for assessing therapeutic effects is currently lacking. This study aims to review the existing noninvasive efficacy evaluation tools for facial rejuvenation and analyze their advantages ...

Growth of Soot Volume Fraction and Aggregate Size in 1D Premixed C2H4/Air Flames Studied by Laser-Induced Incandescence and Angle-Dependent Light Scattering

open access: yesJournal of Combustion, 2018
The growth of soot volume fraction and aggregate size was studied in burner-stabilized premixed C2H4/air flames with equivalence ratios between 2.0 and 2.35 as function of height above the burner using laser-induced incandescence (LII) to measure soot ...

Laser-induced incandescence for soot-particle sizing at elevated pressure

open access: yesApplied Physics B, 2007
This paper describes the applicability of laser-induced incandescence (LII) as a measurement technique for primary soot particle sizes at elevated pressure. A high-pressure burner was constructed that provides stable, laminar, sooting, premixed ethylene/air flames at 1–10 bar.

Heating of nanoparticles and their environment by laser radiation and applications

open access: yesNanotechnology and Precision Engineering
This review considers the fundamental dynamic processes involved in the laser heating of metal nanoparticles and their subsequent cooling. Of particular interest are the absorption of laser energy by nanoparticles, the heating of a single nanoparticle or
