Yanma Y?ntemi ile Lantanit Katk?l? Borat Nano Taneciklerin Sentezi ve Lüminesans ?zelliklerinin ?ncelenmesiKeywords: Lüminesans,Borat,Lantanit Abstract: In this work, luminescent borate particles were synthesized using different lanthanides (Eu, Dy, Nd). An easy, inexpensive and efficient combustion method has been used to synthesize lanthanide-doped luminescent materials. The effects of photoluminescence (PL) spectroscopy on the radiant intensities of lanthanides, trap depths and activators and co-activators were investigated in the synthesized materials. Structural analyzes were performed by X-ray diffraction (XRD), FTIR, Scanning Electron Microscopy (SEM) analyzes. When the damping times of the crystal structure and the compounds are examined according to the addition ratios of the different activators, it has been revealed that each activator influences the afterglow time and decay curve of the different additive ratios. Optimum ratios were determined for each compound. It was observed that the lifetime for the highest values of long lasting afterglow intensity as a result of the lifetime time studies for the substances having the best long lasting afterglow among the synthesized substances is accordingly longer
