TL;DR: Efficient organic-inorganic perovskite light-emitting diodes were made with nanograin crystals that lack metallic lead, which helped to confine excitons and avoid their quenching.

TL;DR: In this article, an efficient organic photovoltaic cell based on a heterojunction of pentacene and C60 was fabricated, which exhibited broad light-harvesting throughout the visible spectrum with a peak external quantum efficiency (EQE) of 58±4% at short-circuit condition.

TL;DR: In this paper, a one-dopant alloying strategy was proposed to generate smaller, monodisperse colloidal particles (confining electrons and holes, and boosting radiative recombination) with fewer surface defects.

TL;DR: In this paper, a facile route to fabricate a built-in haze glass-fabric reinforced siloxane hybrid (GFRH) film having high total transmittance and high haze was reported using the scattering effect induced by refractive index contrast between the glass fabric and the hybrimer.

TL;DR: This Review describes emerging multifunctional materials critical to the advent of next-generation implantable and wearable photonic healthcare devices and discusses the path for their clinical translation, along with the future research directions for the field, particularly regarding mobile healthcare and personalized medicine.
