PHOTOLUMINESCENCE PROPERTIES OF Nd3+, Yb3+ CODOPED Ga2O3 NANOPARTICLES

The availability of sensitive photon detectors and inexpensive lasers allowed us to explore more efficient fluorescent probes that will work in the second near-infrared optical window. In this study, the optical properties of Nd3+ and Yb3+ co-doped Ga2O3 nanoparticles were studied. In order to indicate the correlation between particle size, crystallinity, and optical property of present samples XRD, TEM, and Photoluminescence analyses were performed. Various excitation wavelengths and dopant concentrations were used to understand the energy transfer mechanism in Nd3+ and Yb3+ co-doped Ga2O3 nanoparticles. As the excitation wavelength increased from 325 nm to 477 and 515 nm, Yb3+ emission peak intensity decreased while Nd3+ emission peak intensity increased. This inverse relationship between the emission intensities of Yb3+ and Nd3+ ion showed the presence of energy transfer between them. The resulting emission peaks were broad and weak, indicating the presence of a non-radiative decay channel due to the crystal defects.
