Advanced Functional Materials, EarlyView.A novel low‐bandgap random terpolymer is designed for narrow band detection in charge collection narrowing (CCN) based organic photodetectors. With a relative thin active layer (<1 µm), the CCN‐based devices achieved a narrowband response of 68 nm full‐width‐at‐half‐maximum at 916 nm, together with Responsivity values of 0.13 A W−1 and dark current of ...

Enhancement of Photoluminescence In ZnO/GQD Nanocomposites for Bioimaging Applications
JIF (Jurnal Ilmu Fisika)The synthesis of ZnO/GQD nanocomposites aims to increase ZnO photoluminescence by conjugating techniques with other luminescent materials, namely graphene quantum dot (GQD). This material is applied as a bioimaging material.

Trace Explosives Detection by Photoluminescence
The Scientific World Journal, 2004 Some field tests in counter-terrorism efforts to detect explosive traces employ chemistries that yield colored products. We have examined a test kit of this kind, ETKPlus, based on widely used chemistries and employed extensively by the Israel Police ...

Topological nanophotonics for photoluminescence control [PDF]
, 2020 Rare-earth doped nanocrystals are emerging light sources used for many applications in nanotechnology enabled by human ability to control their various optical properties with chemistry and material science. However, one important optical problem -- polarisation of photoluminescence -- remains largely out of control by chemistry methods.

Heat Conduction Modulation in Incommensurate Twisted Stacking of Transition‐Metal Dichalcogenide
Advanced Functional Materials, EarlyView.The interlayer thermal conductance in twisted bilayer TMDs is initially investigated experimentally by the thermoreflectance method. The overlap of lattice vibrations within individual layers and the interlayer interactions, as elucidated through both Raman spectroscopy and molecular dynamics simulations, are demonstrated to be critical factors in ...

Tunable Tactile Synapses Enabled by Erasable Doping in Iongel‐Gated Nanotube Network Transistors
Advanced Functional Materials, EarlyView.Artificial tactile synaptic sensors are realized by an iongel‐gated single‐walled carbon nanotube (SWCNT) transistor with reversible doping characteristics. The device senses and memorizes tactile stimuli and exhibits gate bias‐dependent excitatory or inhibitory synaptic behavior.

Effects of precursor concentration and reaction time on sonochemically synthesized ZnO nanoparticles [PDF]
Materials Research, 2013 The sonochemical reaction between Zn(NO3)2 and hexamethylenetetramine (HMT) resulted in different products depending on amounts of Zn(II) cations in the aqueous solution. Crystalline phase pure ZnO nanoparticles were obtained by using 0.05 M Zn(NO3)2-HMT.
