Abstract: The synthesis and photoluminescence study of Dysprosium (Dy) doped Calcium Gadolinium Borate Ca3Gd2(BO3)4:Dy3+ are presented in this research. The aim of this study was to investigate the optical properties and potential applications of Dy-doped Calcium Gadolinium Borate as a luminescent material. The samples with Dy+3 doping have been synthesized by the solid state reaction method at varying concentration of Dy+3 ions. The phase purity of the synthesized samples was confirmed from the X-ray diffraction where single phase orthorhombic structure was obtained. The UV excitation photoluminescence spectra of synthesized samples and emission peaks referring to the energy transition of Dy+3 ions are identified. Here, different emission intensities and the shift in the peaks position with reference to change in the Dy+3 concentration were analyzed, and the maximum luminescence intensity was observed at the best dopant concentration. This is made evident from this concentration-dependent behavior which suggests that energy transfer from the host lattice to Dy+3 ions is highly efficient. Therefore, the present work is a successful path towards Dy-doped Calcium Gadolinium Borate as a luminescent material. Due to its property this material seems to have good application potential in solid-state lighting, display and opto-sensing.
