Localization of light is the photon analog of electron localization in disordered lattices, for whose discovery Anderson received the Nobel prize in 1977. The question about its existence in open three-dimensional materials has eluded an experimental and

We present a model calculation for the dependence of the near-band-edge photoluminescence (NBEPL) on the power of the exciting laser light. Our model explains all features of the NBEPL power dependence that were previously observed in experiment: (i) the variation of the excitonic photoluminescen...

We report, for the first time, on the strain related features of the near band-edge luminescence of ZnS epilayers and find emissions that can be related to both heavy-hole (hh) and light-hole (lh) character. Layers with different relative strain show well resolved peaks due to the recombin...
Silicon that offers both high refractive index and mature nanofabrication technology, was shown to enable achromatic metalenses with efficiencies up to 50–60% in the spectral range from 1000 to 1800 nm (squares in Fig. 1)19. At shorter wavelengths above the band edge, the metasurfaces’ ...
For example, recently Xiaomi launched Mi Band 5 wrist band, which supports NFC based payments and transactions through the band. Currently, in the time of COVID-19 pandemic, Silicon Craft Technology PLC (SICT) has launched an NFC enabled wearable band to track COVID-19 patients and those ...
Thin films of nickel-doped zinc oxide (Zn1-NiO) show redshift in the optical band gap and in the near band edge (NBE) emission of the photoluminescence spectra. The Zn1-NiO thin films obtained by sol-gel spin coating method show narrowing of the band gap from 3.23 to 3.00 eV as the...
the PBG through its coupling to the atomic transition near the photonic band edge (the “near” transition) via the Λ configuration. As a result of this coupling, spontaneous emission through the “far” transition can be used as a probe to measure the strength of the effects of the PBG ...
