Abstract

Road lines are those drawn on the veneer with the purpose of driving the vehicles regularly and safely. In addition, parking spaces are intended to mark the places where vehicles will be left, to ensure safe passage of traffic, and to warn drivers against upcoming threats.Alkali-earth aluminates are excellent structures for continuous radiation, especially when doped with rare earth or transition metal ions. Phosphors of CaAl2O4: Eu, Nd continue to be emit phosphorscence light in the dark for a long time after being stimulated by sunlight or artificial light. It is generally believed that the phosphorscence of Eu2+ is due to the 4f to 5d transition. The doped CaAl2O4 : Eu, Nd phosphors were prepared at 550 °C using urea, an organic fuel. Crystal structures of the phosphors were investigated using X-ray diffraction (XRD) and morphology was determined by scanning electron microscope (SEM).The use of these phosphors, which emit in the dark during the night, was investigated in the ways that are difficult to see at night

Özet

Yol çizgileri, araçların düzenli ve güvenli şekilde seyretmeleri amacı ile zemin üzerine çizilen çizgilerdir. Ayrıca, park yeri olarak ayrılmış alanlarda, araçların bırakılacağı yerleri belirlemek, yayaların emniyetle geçişlerini sağlamak ve yaklaşan tehlikelere karşı sürücüleri ikaz amacı ile çizilen işaret çizgileridir. Bu amaçla, sürekli ışıma gösteren fosfor ışıl malzemeler, yol çizgileri için çok önemli çözümlerdir. Alkalitoprak alüminatlar, özellikle nadir toprak veya geçiş metali iyonlarıyla katkılandığında, sürekli ışıma için mükemmel yapılardır. CaAl2O4: Eu, Nd fosforların, güneş ışığı veya yapay ışıkla uyarıldıktan sonra, karanlıkta uzun süre ışımaları devam eder. Çoğunlukla Eu2+'nin fosforesansının 4f-----5d geçişinden kaynaklandığı düşünülür. Katkılanmış CaAl2O4: Eu, Nd fosforları, organik bir yakıt olan üreyi kullanarak, 550°C yanma sıcaklığında hazırlanmıştır. Fosforların kristal yapıları X-ışını kırınımı (XRD) kullanılarak araştırılmış ve morfolojisi taramalı elektron mikroskopu (SEM) ile belirlenmiştir. Gece boyunca karanlıkta ışıma yapan bu fosforların, gece görüş zorluğu olan yollarda kullanım olanakları araştırılmıştır
