Synthesis and optical properties of Ce-doped ZnO hexagonal nanoplatelets

Structural, diffused reflectance and photoluminescence study of cerium doped ZnO nanoparticles synthesized through simple sol–gel method

“…Excitation with 300 and 350nm light yield different sets of emission bands (' Table 2 The UV emission originates from near-band-edge transitions in ZnO, while visible emission can be attributed to defects [52,53]. It has been previously reported that Ce doping results in the change of the ratio of UV and visible emission, but no new additional peaks have been observed [54][55][56]. Cerium doping can change the optical properties and thus it is of potential interest for device applications to obtain devices with different behavior and emission spectra.…”

Structural, magnetic and optical properties of a dilute magnetic semiconductor based on Ce 1−x Co x O 2 thin film grown on LaAlO 3

“…One may notice that the transmittance spectra of the Co-doped cerium oxide thin films exhibited valleys and peaks owing to the interference effect. The Swanepoel method (envelop method) [23] was employed to estimate the optical constants of these films from the transmittance spectra. To evaluate precisely the position of the valleys, T m (), and peaks, T M (), an envelope was made by parabolic interpolation as indicated in Fig.…”

Synthesis and characterization of thin shell hollow sphere NiO nanopowder via ultrasonic technique

“…This indicates that TBAB strongly controls the size of the nickel oxide powders. The average particle sizes (R) were calculated by using Scherrer's formula [22] …”
