| Description | Journal: Materials Research Express This paper reports the synthesis of neodymium (Nd)-doped calcium tungstate $(CaWO_{4}$) nanocrystals (NCs). The thus synthesized NCs were analyzed for phase identification using x-ray diffraction (XRD). The XRD pattern reveals that the formed NCs are in the $I4_{1}$/a space group, and their average size is around 47 nm. A scanning electron microscope (SEM) image shows that the NCs are in the form of rectangular shapes. The presence of rare earth ions in the $Nd:CaWO_{4}$ NCs is confirmed by energy dispersive analysis of the x-rays (EDAX). To further confirm the presence of rare earth ions, photoluminescence and photoluminescence excitation studies were carried out on these NCs. Emissions related to $Nd^{3+}$ ions were observed under 587 nm excitation, and the peaks were assigned to the characteristic$ $^{4}F_{3/2}–^{4}$I_{9/2}$,$ $^{4}F_{3/2}–^{4}$I_{11/2}$ and$ $^{4}F_{3/2}–^{4}$I_{13/2}$ transitions of the Nd ions. |
