Ensuring the thermal reliability of luminescent materials is a key requirement for next-generation lighting, display, and sensing technologies. The intricate interplay of thermal crossover and thermal ionization in lanthanide-doped phosphors often obscures their individual contributions. We present a frequency-domain photoluminescence analysis that disentangles these competing mechanisms. Using single crystals of SrAl2O4:Eu2+,Dy3+ (SAO:Eu,Dy) and (Gd0.33Y0.67)3Al2.4Ga2.6O12:Ce3+,Cr3+ (GYAGG:Ce,Cr)…
The design of advanced materials often reveals how apparent imperfections, such as structural defects or impurities, can be transformed into functional advantages. In insulating oxide matrices, the controlled introduction of dopant ions is the first step toward efficient photoluminescence. Later, the engineering of additional defects, often detrimental for photoluminescence, gives rise to unique capabilities for…
We demonstrate robust exciton-polariton formation in planar metallic optical cavities incorporating porphyrin-based Metal-Organic Framework (MOF) nanoparticles. Our fabrication strategy employs highly monodisperse fluorinated MOF nanoparticle monolayers, sequentially coated with transparent silicon dioxide nanoparticles, enabling precise control over film thickness while preserving MOF pore accessibility. This architecture ensures well-defined excitonic transitions and facilitates alignment of the…
Frequency-domain techniques offer a powerful means to disentangle overlapping physical processes with distinct characteristic timescales-yet remain underexplored in the context of complex photoluminescent materials. Here, frequency-domain analysis is applied to persistent luminescence (PersL) materials, which exhibit long-lasting emission following excitation due to charge trapping and detrapping processes spanning wide temporal ranges. Using SrAl2O4:Eu2(+),Dy3(+) (SAO:Eu,Dy) as…
The substitution of silicon into SrAl2O4 is of interest for the development of new persistent luminescence phosphors with complementary excitation and emission wavelengths, especially in the form of transparent ceramics or glass-ceramics by the glass-crystallization approach. Application of this approach to the series Sr1-x/2Al2-xSixO4 (0 <= x <= 1) has previously produced two different solid…
Lead halide perovskite nanocrystals (NCs) are promising materials for next-generation optoelectronic devices due to their exceptional optical properties. However, poor long-term stability remains a major challenge. In this study, formamidium lead bromide (FAPbBr3) NCs are embedded in a mesoporous silica matrix to enhance stability and explore exciton transport mechanisms. These NCs display a narrow photoluminescence…
