WebbIn addition, the perovskite PL intensity was improved by the high-power BLED backlight. The resulting PL intensity of the Ag@SiO2 nanoparticle-embedded nanorod white LED was 62% greater than that of a planar white LED. AB - White light-emitting diodes (LEDs) are great candidates for general lighting. Webb15 okt. 2024 · For example, red InGaN light-emitting diodes (LEDs) are typically grown by metal-organic chemical vapor deposition (MOCVD) at temperatures ranging from 700 to 765°C. Unfortunately, low-temperature growth also generates higher defect densities, increases impurity incorporation, and degrades surface morphology.
