    Zinc oxide nanostructures enhanced photoluminescence by carbon-black nanoparticles in Moiré heterostructures by Chih-Chiang Wang, An-Ya Lo, Ming-Che Cheng, Yu-Sung Chang, Han-Chang Shih, Fuh-Sheng Shieu, He-Ting Tsai

    Published 2023-06-01
    “…Measurements of optical absorptance revealed that the optical band gap of the ZnO/carbon-black heterostructures increased from 2.33 to 2.98 eV as the carbon-black nanoparticle content increases from 0 to 8.33 × 10−3 mol owing to the Burstein–Moss effect. The photoluminescence intensities at the near-band edge and of the violet, and blue light were increased by factors about 68.3, 62.8, and 56.8, respectively, when the carbon-black contents is of the 2.03 × 10−3 mol. …”
