Ünlü, Bekir Asilcan; Karatay, Ahmet; Yıldız, Elif Akhüseyin; Yola, Mehmet Lütfi; Yüksek, Mustafa; Atar, Necip; Elmalı, Ayhan (Elsevier, 2021)Defect-assisted nonlinear absorption (NLA) and optical limiting (OL) performance of hexagonal boron nitride nanosheets (h-BNNS) in aqueous suspension and in polymethyl methacrylate matrix (PMMA) as nanocomposite films were ... -
Mechanisms of nonlinear optical absorption in (GeO2)1-x–(PbF2)x (0.1 ≤ x ≤ 0.3) modified germanate glasses
Ünlü, Bekir Asilcan; Bilir, Gökhan; Yüksek, Mustafa; Karatay, Ahmet; Yıldız, Elif Akhüseyin; Elmalı, Ayhan (Elsevier, 2022)The structural, optical, and nonlinear absorption properties of (GeO2)1-x–(PbF2)x (0.1 ≤ x ≤ 0.3) glasses synthesized by conventional melting and quenching technique were investigated. Bandgap energies and Urbach energies ...
