Abstract

Hexagonal boron nitride (hBN) with luminescent properties was synthesized by heat treatment of boric acid, melamine, Eu+3 and Dy+3 at 1200 °C for 1 hour. When boron nitride was excited with UV light, the presence of Eu+3 and Dy+3 ions showed emission from blue to red. The formulation with the highest energy efficiency was determined by using different [Dy+3 / Eu+3] ratios. Emission with high energy efficiency (~0.83) was observed at a rate of [Dy+3 / Eu+3] = 0.5. In addition, it was observed that the luminescence intensity decreased with the increase of the amount of Dy+3 ions. The formation of the non-emitting dysprosium borate (DyBO3) phase effected the luminescence property negatively.

Özet

Lüminesans özellik gösteren hekzagonal bor nitrür (hBN) borik asit, melamin Eu+3 ve Dy+3 ‘un 1200 °C’de 1 saat ısıl işlemi ile sentezlendi. Bor nitrür UV ışık ile uyarıldığında Eu+3 ve Dy+3 iyonlarının varlıkları maviden kırmızıya emisyon göstermiştir. Farklı [Dy+3 / Eu+3] oranları kullanılarak enerji verimliliği en yüksek olan formülasyon belirlenmiştir. Yüksek enerji verimliliğine (~0,83) sahip emisyon [Dy+3 / Eu+3] = 0,5 oranında görülmüştür. Ayrıca Dy+3 iyonlarının miktarının artmasıyla ışıldama yoğunluğunun azaldığı görülmüştür. Işıldama göstermeyen disprozyum borat (DyBO3) fazının oluşumu lüminesans özelliği olumsuz etkilemiştir.
