To develop Dy doped silica glass with a higher irradiation resistance, which can be adapted to high power violet or blue LD pumped yellow laser fibers, the designed Dy-Al-Ce codoped silica glasses, 0.05Dy 2 O 3 -1.5Al 2 O 3 -xCe 2 O 3 -(98.45-x)SiO 2 (x = 0, 0.05, 0.1, 0.25, 0.5), were prepared by the sol-gel method. Their excitation spectra, emiss...

All-inorganic CsPbBr3 perovskites have gained significant attention due to their potential in direct X-ray detection. The fabrication of stable, pinhole-free thick films remains challenging, hindering their integration in durable, large-area high-resolution devices. In this study, we propose a facile strategy using a non-conductive polymer to creat...
The understanding of lanthanide-related electron transfer processes is crucial for designing efficient and functional luminescent phosphors. However, the current knowledge on those processes between Eu ions with different oxidation states is rather scarce, which limits the progress of developing new efficient phosphors with good stability. In this ...
This work deals with research and optimization of the optical Ge-Si glass composition doped with Er3+, Yb3+ ions and bismuth optically active centers (BACs), which are optically active for implementation in a double C- and U-band planar optical amplifier. The intention was to increase the range of amplified wavelengths in the NIR band up to 1650 nm...

We report luminescence decay characteristics of the InGaN/GaN scintillator heterostructures doped with Zn. Unusually large shifting of luminescence band caused by Zn acceptors incorporated in InGaN is observed both in time-resolved and excitation-dependent spectra. Origins of the shifts are discussed, and model based on donor-acceptor pair recombin...

A new phosphor particle streak velocimetry (phosphor-PSV) diagnostic with high spatial resolution was recently demonstrated (Fan et al. in Opt Lett 46:641, 2021), where individual phosphor particles, excited by a short pulse laser, form streaks as a results of their displacement by the flow during their relatively long luminescence decay. The local...
Transparent Ce:lutetium aluminum garnet (Ce: Lu3Al5O12, Ce:LuAG) ceramics have been regarded as potential scintillator materials due to their relatively high density and atomic number (Z(eff)). However, the current Ce:LuAG ceramics exhibit a light yield much lower than the expected theoretical value due to the inevitable presence of Lu-Al antisite ...
