ZnS-based photonic crystal phosphors fabricated using atomic layer deposition
The infiltration by atomic layer deposition of three-dimensional opal structures has been investigated as a means of fabricating photonic crystal phosphors. ZnS:Mn infiltrated and inverse opals have been demonstrated with filling fractions >95%. Characterization of these structures by scanning electron microscopy, specular reflectance, and photoluminescence is reported. Specular reflectance mea...
متن کاملOptically pumped distributed feedback dye lasing with slide-coated TiO₂ inverse-opal slab as Bragg reflector.
We demonstrate an optical amplification of organic dye within a TiO2 inverse-opal (IO) distributed feedback (DFB) reflector prepared by a slide-coating method. Highly reflective TiO2 IO film was fabricated by slide coating the binary aqueous dispersions of polystyrene microspheres and charge-stabilized TiO2 nanoparticles on a glass slide and subsequently removing the polymer-opal template. TiO2...

متن کاملMono-Mono-Mono and Bi-Bi-Bi three-layer graphene systems’ optical conductivity
Investigating the longitudinal optical conductivity of graphene systems, which is the mostimportant property for opto-electronic devices, for three-layer graphene systems theoretically and numerically is the main purpose of this study. Each layer can be mono- or bi-layer graphene. Separation between layers has been denoted by d, selected to be about ten nanometers. The carrier densities i...
متن کاملFive-Fold Reduction of Lasing Threshold near the First ΓL-Pseudogap of ZnO Inverse Opals
We report room temperature lasing in ZnO inverse opal photonic crystals in the near-ultraviolet (UV) frequency. We observe random lasing due to disorder in the structures when the photonic pseudogaps are located away from the ZnO gain spectrum. Tuning the first ΓL-pseudogap to the gain peak leads to a five-fold reduction in lasing threshold and frequency shift of lasing modes due to the enhance...
