Dynamics in blue emitting metal halide perovskites for light emitting diodes by Karlsson, Max

“…Although the origins of the poor temporal stability of perovskite light emitting diodes are manifold, one of the main problems are the low barriers for halide migration under the applied electric field during operation, rapidly degrading the device properties. We first find that compositional heterogeneities, stemming from rapid uncontrolled film growth, both lowers the threshold for further halide segregation as well as serves as centers for non-radiative recombination, resulting in reduced luminescence yield. …”

Lifshitz interaction can promote ice growth at water-silica interfaces by Boström, Mathias, Malyi, Oleksandr I., Parashar, Prachi, Shajesh, K. V., Thiyam, Priyadarshini, Milton, Kimball A., Persson, Clas, Parsons, Drew F., Brevik, Iver

“…At air-water interfaces, the Lifshitz interaction by itself does not promote ice growth. On the contrary, we find that the Lifshitz force promotes the growth of an ice film, up to 1–8 nm thickness, near silica-water interfaces at the triple point of water. …”

Computational study of power conversion and luminous efficiency performance for semiconductor quantum dot nanophosphors on light-emitting diodes by Erdem, Talha, Nizamoglu, Sedat, Demir, Hilmi Volkan

“…We present power conversion efficiency (PCE) and luminous efficiency (LE) performance levels of high photometric quality white LEDs integrated with quantum dots (QDs) achieving an averaged color rendering index of ≥90 (with R9 at least 70), a luminous efficacy of optical radiation of ≥380 lm/Wopt a correlated color temperature of ≤4000 K, and a chromaticity difference dC <0.0054. We computationally find that the device LE levels of 100, 150, and 200 lm/Welect can be achieved with QD quantum efficiency of 43%, 61%, and 80% in film, respectively, using state-of-the-art blue LED chips (81.3% PCE). …”

Ion irradiation to control size, composition and dispersion of metal nanoparticle exsolution by Wang, Jiayue, Woller, Kevin B., Kumar, Abinash, Zhang, Zhan, Zhou, Hua, Waluyo, Iradwikanari, Hunt, Adrian, LeBeau, James M., Yildiz, Bilge

“…Here, we present ion irradiation as a general platform to allow control over these parameters during metal nanoparticle exsolution, by simultaneous sputtering, implantation, and defect generation mechanisms. Using thin-film perovskite and binary oxides as model systems, we showed ion beams can controllably reduce the size of exsolved nanoparticles down to 2 nm through ion sputtering. …”
