Effect of modifier oxides on spectroscopic and optical properties of Pr3+ doped PbO-Ro2O3-WO3-B2O3 glasses (with Ro2O = Sb2O3, Al2O3, and Bi2O3)
(2020-09-28)
Article
Restricted access - publisher's policyPraseodymium (Pr2O3) doped PbO-Ro2O3-WO3-B2O3 glasses were prepared by melt quenching method and their optical absorption and emission spectra were characterized, for three different heavy metal oxides (Ro2O3 = Sb2O3, ... -
Ergodic Light Propagation in a Half-Cylinder Photonic Plate for Optimal Absorption in Perovskite Solar Cells
(2019-05-17)
Article
Open AccessIn an optical medium slab, a randomization of the interfaces will lead to an ergodic light propagation, implying a kind of light trapping that sets an upper limit for a broadband absorption enhancement factor. However, in ... -
Inverse Optical Cavity Design for Ultrabroadband Light Absorption Beyond the Conventional Limit in Low-Bandgap Nonfullerene Acceptor–Based Solar Cells
(2019-05-23)
Article
Open AccessIn the subwavelength regime, several nanophotonic configurations have been proposed to overcome the conventional light trapping or light absorption enhancement limit in solar cells also known as the Yablonovitch limit. It ... -
Plasmonically enhanced light absorption in graphene nanoribbons
(Universitat Politècnica de Catalunya, 2012-09-06)
Master thesis
Open Access[ANGLÈS] Light absorption plays a crucial role in both optical detectors and photovoltaics. In order to improve the light absorption properties of materials different measures can be taken. This thesis considers light ... -
Role of the spectral shape of quantum correlations in two-photon virtual-state spectroscopy
(2013-05)
Article
Open AccessThe true role of entanglement in two-photon virtual-state spectroscopy (Saleh et al 1998 Phys. Rev. Lett. 80 3483), a two-photon absorption spectroscopic technique that can retrieve information about the energy level ... -
Tunable complete optical absorption in multilayer structures including 𝐆𝐞𝟐𝐒𝐛𝟐𝐓𝐞𝟓 without lithographic patterns
(Wiley, 2017-01-04)
Article
Open AccessControlling the spectral transmission, reflection, and absorption properties of optical structures is of great interest for many applications in photonics. Particularly, perfect absorbers over a wide frequency (wavelength) ...
