Abstract

Barium calcium sulfate dysprosium dope is investigated by the combustion method, and their systems
are exposed. The morphology characterization is done with Scanning Electron Microscope (SEM) analysis and
average crystalline size by X-Ray Diffraction (XRD). Photoluminescence and thermoluminescene properties
and their quantities were confirmed with Dysprosium mixed material. The emission and excitation values of
photoluminescence are 368 nm and 394 nm respectively. Using this wavelength, its emission wavelength
produces a white color. These are the f-f type that moves from one place to another and the ground emission is
4
f9/2. The absorption intensities of high quantum efficiency peaks related to small multi-functional relaxation
were recognized due to the energy gap in the region between the next 6H15/2. With such a spectrum, the blue and
yellow-white emissions of phosphorus were combined to give a cool-white light, and thermoluminescence
studies obtained by trapping parameters were calculated.
