Nd+ 3 ions effects on the blue emission of colloidal Y(OH)3 nanobelts.

In this report, we synthesized the neodymium-doped yttrium hydroxide nanobelts (Nd:Y(OH)3) using a facile route. The characterization methods, such as UV-Visible and photoluminescence spectroscopy, Raman, X-ray photoemission, Fourier transform infrared (FTIR) spectroscopy, and high resolution transmission electron microscopy (HRTEM), were applied to clarify the properties of the prepared colloidal sample. The structural characteristics of the prepared sample were analyzed via X-ray diffraction (XRD) and HRTEM. The average size of the hexagonal crystal is about 25 nm, which shows the compatibility of XRD and HRTEM spectroscopy results. Absorbance and emission spectra of the synthesized sample have demonstrated that the intensity of light emission by the colloidal sample is affected by the concentration of Nd3+ ions. In this research, it has been shown that the excitation of the samples with the wavelengths of 355 and 360 nm almost does not change the blue emission spectra because the wavelengths are related to the nature of the Nd+ 3, but with the excitation of 300 nm, the intensity of the emission spectra increases with the increase in the concentration up to 0.05 g (sample 2).
