In this study, Sn-doped 10HfO2–10Al2O3–80SiO2 glasses were prepared using a xenon imaging furnace and their physical, optical, and scintillation properties were investigated. At the composition ratio, the specimens did not completely vitrify, and they were crystallized glasses that contained nanocrystals of c-HfO2. Raman spectra show the absorption...

The fundamental defects around the p–n interface were analyzed based on low temperature photoluminescence measurements to determine the origin of the various defects around the n-CdS/p-SnS structure in tin sulfide (SnS) solar cells. Particularly, the effects of Cd, S, and Na atoms on PL at the interface of a CdS layer and various treated SnS layers...

Graphene and its relatives have received considerable attention from the fields of physics and chemistry since the isolation of pristine graphene sheets. Nanographenes (NGs) are graphene fragments that are a few to tens of nanometers in diameter. Compared to graphene and its relatives, such as graphene oxides, NGs can be handled more easily, and th...

The recent observation of room temperature spin-dependent photoluminescence (PL) emission from hexagonal boron nitride’s (h-BN’s) defect centers motivates for performing a complementary low-temperature photophysical study of quantum emitters under relatively high magnetic fields. Here, we investigate the PL emission dynamics of h-BN’s visible singl...

Metal halide perovskites possess exciting optoelectronic properties and are being used for various applications, including fluorescent anticounterfeiting security tags. The existing anticounterfeitings based on perovskites have a reversible transition that does not allow to know whether the information is tampered or compromised. In this work, we d...

The negatively charged silicon vacancy V S i − $\left({\mathrm{V}}_{\mathrm{S}\mathrm{i}}^{-}\right)$ in silicon carbide is a well-studied point defect for quantum applications. At the same time, a closer inspection of ensemble photoluminescence and electron paramagnetic resonance measurements reveals an abundance of related but so far unidentified...

After the discovery of graphene in 2004, two dimensional (2D) materials have fascinated a lot of view due to the excellent properties. Nowadays, the research on 2D materials has spread to other graphene-like layer structured materials, especially transition metal dichalcogenides (TMDCs). Tin disulfide (SnS2) is a kind of TMDCs with a sizable bandga...

Over the past few decades, photodynamic therapy has been studied as a therapeutic method by generating singlet oxygen through activation of a photosensitizer (PS) to kill cancer cells. However, the light within the activating wavelength range of commercial photosensitizers has a low penetration depth. In this study, we designed multifunctional upco...

Self-assembled InAs/InAsSb ultrahigh-density quantum dots (UHD QDs) were grown on GaAs(001) substrate by molecular beam epitaxy. The QD density was 1 × 1012 cm−2, and an average separation distance between adjacent QD edges was less than 3 nm. The temperature dependence of photoluminescence (PL) minimum energy of UHD QDs was measured and was divide...
