Blue Phase: Shining Star of Liquid Crystals

Abstract

Mavi Faz: Sıvı Kristallerin Parlayan Yıldızı

Abstract

Bu çalışmada mavi faz sıvı kristallerin fiziksel özellikleri, fotonik ve optik uygulamaları hakkında genel bir bilgi verilmiştir. Mavi faz, izotropik sıvı ile kolesterik faz arasında bulunan bir sıvı kristal fazıdır. Çift bükümlü her bir silindirik yapı bu sistemin temel birimini oluşturur ve kendi kendine birleşerek üç boyutlu bir yapı meydana getirirler. Geleneksel bir sıvı kristal ile karşılaştırıldığında; milisaniyenin altında tepki hızı, herhangi bir hizalama katmanına ihtiyaç duymaması, optiksel olarak izotropik olması, ekranlar için geniş bir görüş açısı sağlaması ve hücre kalınlığına duyarlı olmaması mavi faz sıvı kristallerin kendine özgü fiziksel üstünlükleridir. Mavi faz sıvı kristaller bahsedilen bu avantajlarından dolayı optik sistemlerde, görüntüleme cihazlarında ve diğer benzeri uygulama alanlarında belirgin bir kullanım potansiyeline sahiptir.
