The Game is On! The Adventure of the Girl with the Light Blue Hair

The Game is On! is a series of short animated films that put copyright and creativity under the magnifying glass of Sherlock Holmes, providing a unique, research-led and open access resource for school-aged learners and other creative users of copyright. Drawing inspiration from well-known copyright and public domain work, as well as recent copyright litigation, these films provide a springboard for exploring key principles and ideas underpinning copyright law, creativity, and the limits of lawful appropriation and reuse.

Each episode comes accompanied by a number of related Case Files: supplementary educational materials aimed at suggesting points of discussion about copyright for teachers and students.

Efficient Blue Electroluminescence Using Quantum-Confined Two-Dimensional Perovskites

Solution-processed hybrid organic–inorganic lead halide perovskites are emerging as one of the most promising candidates for low-cost light-emitting diodes (LEDs). However, due to a small exciton binding energy, it is not yet possible to achieve an efficient electroluminescence within the blue wavelength region at room temperature, as is necessary for full-spectrum light sources. Here, we demonstrate efficient blue LEDs based on the colloidal, quantum-confined 2D perovskites, with precisely controlled stacking down to one-unit-cell thickness (n = 1). A variety of low-k organic host compounds are used to disperse the 2D perovskites, effectively creating a matrix of the dielectric quantum wells, which significantly boosts the exciton binding energy by the dielectric confinement effect. Through the Förster resonance energy transfer, the excitons down-convert and recombine radiatively in the 2D perovskites. We report room-temperature pure green (n = 7–10), sky blue (n = 5), pure blue (n = 3), and deep blue (n = 1) electroluminescence, with record-high external quantum efficiencies in the green-to-blue wavelength region.
