Thermal‐Energy‐Boosted Luminescence for Precise Optical Thermometry in Eu/Tb‐Doped ScNbO4

open access: yesAdvanced Optical Materials, EarlyView.
This paper presents a novel phosphor for high‐performance optical thermometry utilizing thermal‐energy‐assisted luminescence boosting. The samples are prepared by incorporating Eu‐doped ScNbO4 and Tb‐doped ScNbO4 powders into a PDMS matrix. Under blue light excitation, the sample exhibits a stunning emission color change from green to red as the ...

Transition‐Metal Azo Schiff Base Complexes: Nonlinear Optics Across Solutions, Thin Films and Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
The excitation of a transition‐metal azo Schiff‐base complex with a 1064 nm laser induces a series of nonlinear optical effects. These effects include the second harmonic generation at 532 nm and third harmonic generation at 355 nm. This process demonstrates the potential of the complex for high‐order nonlinear optical applications. Abstract This paper

Detection of Hybrid Optical Anapoles in Dielectric Microspheres

open access: yesAdvanced Optical Materials, EarlyView.
In this work, hybrid optical anapoles are detected in dielectric microspehers using dual detection optical spectroscopy. The results show that the excitation of TiO2 microspheres under tightly focused Gaussian Beam illumination leads to the appearence of scattering minima in both the forward and backward directions within specific wavelength ranges ...
