DOI: 10.1002/adfm.202520569

Abstract: The mixed‐halide CsPbCl3‐xBrx perovskite quantum dots (QDs) have emerged as promising candidates for pure‐blue light‐emitting diodes (LEDs). However, the widely existing defects in these mixed‐halide perovskites, arising from uncontrollable crystallization and low Cl vacancy formation… read more here.

DOI: 10.1002/adma.202302161

Abstract: Lead halide perovskites have shown exceptional performance in light-emitting devices (PeLED), particularly in producing significant electroluminescence in sky-blue to near-infrared wavelengths. However, PeLEDs emitting pure-blue light at 465 to 475 nm are still not satisfactory.… read more here.
