The design of next-generation calorimeters for accelerator-borne experiments at the intensity frontier poses unprecedented challenges with regard to timing performance and radiation resistance, while rivaling current state art in terms energy resolution. A significant role may be played by quantum dots, i.e., light-emitting semiconductor nanocrystals high yield rather easy manufacture. Quantum dots can cast into an optically transparent polymer matrix obtain nanocomposite scintillators,...
