The theme of lead-free ammunition has been increasingly gaining coverage in politics and the media. As the European market leader with an internationally established brand, RWS wishes to join in this timely discussion and also offer lead-free ammunition. It was our aim to develop a “green” projectile, which would offer some real product ...
202211 · In 2018, Jun et al. proposed the principle to use the low-cost and pollution-free copper instead of lead. With the all-inorganic Cs 3 Cu 2 I 5, they achieved a bright blue emission at 445 nm with a relatively high PLQY (90% for single crystal and 60% for thin film) [23]. The broadband emission, high PLQY, and large Stokes shift of Cu-based ...
