(Phys.org)—When exposed to air, a luminescent 2D material called molybdenum telluride (MoTe2) appears to decompose within a couple days, losing its optical contrast and becoming virtually transparent. But when scientists ...
Expensive noble metals often play a vital role in illuminating screens or converting solar energy into fuels. Now, chemists at the University of Basel have succeeded in replacing these rare elements with a significantly cheaper ...

In old cathode ray TVs, a picture is generated when an electron beam excites a phosphor screen, causing the phosphor to radiate light. Now in a new study, researchers have found that a beam of positrons (positively charged ...
LEDs have inspired a new generation of electronics, but there is still work ahead if we want luminescent materials to consume less energy and have longer lifespans. Certain inorganic metals seem promising, but they are rare, ...
