However, the random isotropic emission of photons within the device influenced by the interfacial effect of multilayer structures results in mediocre photon out-coupling efficiency, posing a challenge for the continued development of QLEDs. This study introduces asymmetrically strained green CdZnSeS/ZnSeS/ZnS/CdZnS quantum dots (QDs) with a substantial size of 16.0 nm, synthesized through secondary nucleation and thick multi-shells growth strategy, aimed at enhancing the directivity of photon emission in QLEDs. Specifically, the irregular growth of the continuous gradient ZnSeS/ZnS/CdZnS shells imposes asymmetric strains on the CdZnSeS cores, promoting the formation of well-aligned QD films with a horizontal dipole orientation factor exceeding 80 %. This orientation is advantageous for enhancing the photon out-coupling efficiency of the devices. As a result, the QD films exhibit stable emission spectra with an impressive near-unity photoluminescence quantum yield (PLQY) of 98.7 %. Based on these findings, highly efficient green QLEDs were fabricated, achieving a maximum external quantum efficiency (EQE<sub>max</sub>) of 28.8 %, a luminance over 230,000 cd m<sup>−2</sup>, and exceptional operational stability (<em>T</em><sub>95</sub>, tested at 1000 cd m<sup>−2</sup>) of 6350 hours.

This study addressed this limitation by treating cotton with polyethyleneimine (PEI) via scalable pad-dry method. The PEI treatment enhanced tribo-positivity and provided its additional benefits, like antibacterial (83.33 %) and antioxidant (74.2 %) properties. In this work, we explored PEI-treated cotton fabric for T-TENG devices aimed at energy harvesting, self-powered electronics, and physiological movement monitoring. The 10 % PEI-treated cotton T-TENG demonstrated a significant increase in electrical performance, with increments in output voltage and current by 3.4-fold (from ∼30 V to ∼103 V) and 3.27-fold (from ∼3.36 µA to ∼11 µA), respectively, under a contact pressure of 16 N (25.6 kPa) and a frequency of 8 Hz. Additionally, the device achieved a maximum power density of ∼1600 mW/m² at 10 MΩ resistance. The device's practical applications were demonstrated through its ability to charge capacitors of various capacitance values, power a series of more than 70 LEDs and operate off-the-shelf electronics like wristwatch, digital timer, and humidity sensor. Additionally, the T-TENG functioned as a pressure sensor, in monitoring joint movements when attached to body joints (e.g., wrist, elbow, shoulder, knee), offering applications in athlete motion tracking.

The isotropic lithiation behavior of amorphous Sn cluster enables adaptive stress dissipation during cycling, suppressing pulverization.
