Abstract

In this work, luminescent NaCa4-2x(BO3)3: xA1,A2 (A1:A2, Eu: Dy, Nd), (x= 0.03, 0.05 ve 0.07) structures 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. It is generally believed that the phosphorus of Eu2+ is due to the 4f to 5d transition. 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. Structural properties and on light emisssion intensity of the Eu-doped compounds with the most intense luminescence were measured. According to the obtained PL spectra, it has been found that increasing the co-activator concentrations leads to a decrease in the intensity of radiation, contrary to the increasing direction of the emission intensity.

Özet

Bu çalışmada, farklı lantanitler (Eu, Dy, Nd) kullanılararak, lüminesans özellikliNaCa4-2x(BO3)3: xA1,A2 (A1:A2, Eu: Dy,Nd), (x= 0,03, 0,05 ve 0,07) yapısında borattanecikler sentezlenmiştir. Lantanit katkılı lüminesans maddelerin sentezlenmesiiçin, bugüne kadar bir çok çalışmada kullanılan katı hal yöntemi dışında, dahakolay, ucuz ve verimli olan yanma yöntemi kullanılmıştır. Sentezlenen maddelerde,fotolüminesans (PL) spektroskopisi yöntemi kullanılarak katkılanan lantanitlerin,tuzak derinliklerinin ve (aktivatör ve ko-aktivatörlerin) derişimlerinin emisyon şiddetiüzerine etkisi incelenmiştir. Çoğunlukla Eu2+’nin fosforesansının 4f-5d geçişindenkaynaklandığı düşünülmektedir. Yapısal analizler X ışını kırınımı (XRD), FTIR,Taramalı Elektron Mikroskobu (SEM) analizleri ile yapılmıştır. Farklı aktivatörlerinkatkı oranlarına göre, kristal yapı ve bileşiklerin sönüm süreleri incelendiğinde, herbir aktivatörün, farklı katkı oranlarının emisyon şiddeti ve sönüm sürelerini etkilediğiortaya konmuştur. En şiddetli ışıma yapan Eu katkılı bileşiklerin, yapısal özelliklerive emisyon şiddetleri ölçü mleri yapılmıştır. Elde edilen PL spektrumlarına göre, koaktivatörkonsantrasyonlarının arttırılmasının emisyon şiddetinin artırıcı yönün tamtersine, ışıma şiddetinde azalmaya yol açtığı görülmüş tür.
