“…To reduce the ambiguity in determining the coupling constants, we use the experimental data when they are available. As we will show later, the results of the total cross section for the γp → K Ãþ Λ reaction are in remarkable agreement with the new CLAS data [1]. Its differential cross sections are also well reproduced, compared to those from previous works [3][4][5][6].…”

“…Though the original motivation of Ref. [1] was to study the role of κð800Þ mesons involved in the t-channel process, the new CLAS data near the threshold gives us a clue to understanding the role of higher nucleon (N Ã ) resonances. In a previous work [3], it was found that the N Ã resonances indeed played an important role in describing the experimental data near the threshold region.…”

We reinvestigate K Ã Λð1116Þ photoproduction off the nucleon target, based on an effective Lagrangian approach. We include higher nucleon resonances such as Nð2000Þ5=2 þ , Nð2060Þ5=2 − , Nð2120Þ3=2 − , and Nð2190Þ7=2 − , of which the data are taken from the 2012 edition of Review of Particle Physics, in addition to the t-channel diagrams (K, K Ã , and κ), the s-channel nucleon, and u-channel hyperon (Λ, Σ, and Σ Ã ) contributions. We find that the Nð2120Þ3=2 − and Nð2190Þ7=2 − resonances are essential in describing the new CLAS Collaboration data for charged K Ã photoproduction. On the other hand, they rarely affect neutral K Ã photoproduction.

Gallium selenide (GaSe) is a layered compound, which has been exploited in nonlinear optical applications and photodetectors due to its anisotropic structure and pseudodirect optical gap. Theoretical studies predict that its 2D form is a potential photocatalyst for water splitting reactions. Herein, the photoelectrochemical (PEC) characterization of GaSe nanoflakes (single‐/few‐layer flakes), produced via liquid phase exfoliation, for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in both acidic and alkaline media is reported. In 0.5 m H2SO4, the GaSe photoelectrodes display the best PEC performance, corresponding to a ratiometric power‐saved metric for HER (Φsaved,HER) of 0.09% and a ratiometric power‐saved metric for OER (Φsaved,OER) of 0.25%. When used as PEC‐type photodetectors, GaSe photoelectrodes show a responsivity of ≈0.16 A W−1 upon 455 nm illumination at a light intensity of 63.5 µW cm−2 and applied potential of −0.3 V versus reversible hydrogen electrode (RHE). Stability tests of GaSe photodetectors demonstrated a durable operation over tens of cathodic linear sweep voltammetry scans in 0.5 m H2SO4 for HER. In contrast, degradation of photoelectrodes occurred in both alkaline and anodic operation due to the highly oxidizing environment and O2‐induced (photo)oxidation effects. The results provide new insight into the PEC properties of GaSe nanoflakes for their exploitation in photoelectrocatalysis, PEC‐type photodetectors, and (bio)sensors.

high reliability, their internal electroluminescence quantum effi ciency ( η int ), defi ned as the number of photons generated per injected carrier, is limited to 25% because of the exciton-branching ratio of singlet excited states under electrical excitation. [ 2 ] To increase the value of η int , several methods were proposed, such as employing phosphorescent materials with heavy atoms, utilizing triplet-triplet exciton annihilation for extra singlet generation, and employing thermally activated delayed fl uorescence (TADF) materials. [3][4][5][6] In particular, an η int value of 100% is expected by employing phosphorescent and TADF materials. In 1999, effi cient electrophosphorescence was fi rst demonstrated using iridium complexes, and an η int value of almost 100% was achieved afterwards. [ 7,8 ] Many highly effi cient phosphorescent OLEDs (PHOLEDs) with values of η int of about 100% were demonstrated by using a device architecture that can confi ne charges and excitons inside the phosphorescence-emitting layer. [ 9,10 ] Although PHOLEDs have a longer history than OLEDs fabricated with TADF materials, the basic concept for improving both the effi ciency and operational stability is not clear; this is the greatest challenge for the practical application of PHOLEDs.In recent years, several PHOLEDs with high effi ciency and high operational stability were reported. [ 11,12 ] The confi guration of the emitting layer, i.e., the combination of the phosphorescent dopant and the surrounding host material, was proposed as a key parameter determining the effi ciency and stability of PHOLEDs. Particular metal complexes such as bis(benzo[h]quinolin-10-olato-kN,kO)beryllium( II ) (Bebq 2 ) and bis[2-(2-hydroxyphenyl) benzothiazolato]zinc( II ) [Zn(BTZ) 2 ] are effective hosts for red PHOLEDs; however, an effective host for green/blue PHOLEDs with high operational stability was not yet reported. If the role of effective hosts such as metal complexes in a highly effi cient and stable PHOLED is revealed, the development of useful host materials for green/blue PHOLEDs is expected to be accelerated.Herein, to investigate a possible strategy for realizing highly effi cient and stable PHOLEDs, we examine the energy-transfer mechanism in such PHOLEDs. A highly effi cient green PHOLED that exhibits a half lifetime of over 10000 h with an initial luminance of 1000 cd m -2 is realized by using a Phosphorescent organic-light emitting diodes (PHOLEDs) exhibit an internal quantum effi ciency of 100% and their early practical realization is expected. One of the main challenges in PHOLEDs is to improve the operational stability of green and blue devices. Triplet exciton dynamics in stable PHOLEDs, which are different from those in unstable PHOLEDs, are shown. An effi cient and stable green PHOLED is demonstrated by employing a suitable host that surrounds the phosphorescent dopant. The transient photoluminescence characteristics show that the triplet excitons of the host, which are generally unstable, are rapidly transferred to the dop...
