Defect assisted optical limiting performance of hexagonal boron nitride nanosheets in aqueous suspension and PMMA nanocomposite films
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 ... -
Effect of Cr/Sb doping and annealing on nonlinear absorption coefficients of SnO2 /PMMA nanocomposite films
Pepe, Yasemin; Karatay, Ahmet; Donar, Yusuf Osman; Bilge, Selva; Yıldız, Elif Akhüseyin; Yüksek, Mustafa; Sinağ, Ali; Elmalı, Ayhan (Elsevier, 2020)Cr and Sb doped SnO2 nanoparticles were synthesized by hydrothermal method. The structural measurements of as-grown nanoparticles exhibited that the incorporation of the 3% wt. Cr and Sb dopant into the SnO2 crystal structure ... -
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 ... -
Nonlinear optical performance and optical limiting of germanate glasses modified with PbF2 and B2O3 induced by nanosecond pulsed laser
Pepe, Yasemin; Bilir, Gökhan; Yüksek, Mustafa; Karatay, Ahmet; Yıldız, Elif Akhüseyin; Elmalı, Ayhan (Elsevier, 2022)In this work, GeO2 modified with PbF2 and B2O3 glasses were synthesized by conventional melting and quenching technique to investigate the effect of modifier network on its linear and nonlinear optical properties. Linear ...
