Structural Interpretation and Photoluminescence Properties of Sr0:90􀀀xCa0:10Al12O19:Dyx 3+Nanophosphors Synthesis by Combustion system

Received Date:15 November 2021, Accepted Date:08 February 2022, Published Date:14 April 2022


Objectives: To synthesize a phosphor of more intense, high color purity, and to last longer. Methods: We have synthesized Sr0:90􀀀xCa0:10Al12O19:Dy3+ x (x=0.00, 0.01, 0.03, 0.05, 0.07) phosphors using a low temperature (560  10 )◦C combustion system. X-ray diffraction, Field Emission Scanning Electron Microscopy (FE-SEM), and EDS spectra were used to perform phase identification, morphological examination, and elemental analysis. Spectroscopic photoluminescence techniques of the described phosphor were used to investigate its optical properties. Findings: According to scherrer’s formula, the crystal size of strontium calcium aluminates phosphor is between 12.58 and 84.67 nm. The Dy3+ emission peaks at 475 nm (blue), 573 nm (yellowgreen), and 666 nm (red) in the phosphor. PL emission spectra can be attributed to the 4f-4f transition of Dy3+ ions. The phosphor color purity is 15%, and the average life time is 0.96 ms, indicating that it will survive a long last. The intensity at the wavelengths of 475nm and 575 nm is 40000 counts and 35000 counts, respectively. Novelty: With a 0.10 molar calcium concentration, we have synthesized strontium aluminates phosphor with improved properties. The described phosphor has long-lasting applications as a refractory structural material, great and useful material for pale-orange colorants, and may be employed in many solid-state lighting technologies.
