“…Evidently, the lower recording efficiency by focused beams is mainly the result of photoisomerization intensity dependence. As shown by Aleksejeva et al [14], in the case of B8 films, SRG relief modulation amplitude for intensities higher than 0.4 W/cm 2 decreases, and this decrease is very fast for intensities higher than 1 W/ cm 2 . The authors explain this phenomenon by too large photosoftening making film unstable.…”

“…VBG have been recorded much faster than SRG and VDG. Photoinduced birefringence takes place in few seconds whereas relief forms in few hundreds of seconds [14]. Evidently, the lower recording efficiency by focused beams is mainly the result of photoisomerization intensity dependence.…”

Holograms recorded by focused light beams have several advantages over usual plane wave holograms such as reduced size, white light readout possibility and others. Focused polarization grating recording in an azobenzene-based molecular glasy film 5,5,5-triphenylpentyl 4-((4-(2-(4-bis(2-hydroxyethyl)amino)phenyl)-1-cyanovinyl)phenyl)dyazenyl)benzoate (which we shortly denoted as B11) is experimentally studied and compared with such grating recording in other materials. It has been determined that focusing manifests itself differently than in other materials, e.g., as in a-As2S3 and a-As-S-Se chalcogenide films. Thus, it reduces the holographic grating recording efficiency independently of recording and readout beam polarizations. It has also been found that recording efficiency with circularly and orthogonally L-R polarized beams is higher than with linearly polarized p-p beams. The highest diffraction eficiency of 26% is achieved with L-R polarized unfocused beams. Recording efficiency grating period dependences for unfocused beams at 200 J/cm2 exposure and at 1000 J/cm2 exposure are different with a maxima at 2 μm and 6 μm, respectively. In contrast, recording efficiency grating period dependences for focused beams at 200 J/cm2 exposure and at 1000 J/cm2 exposure are the same with the maximum at 6 μm. The obtained results are discussed in terms of trans-cis-trans photoisomerization followed by mass transfer and their light intensity dependence, light electric field gradient force, the photoinduced light scattering and photoelastic forces.

“…Aleksejeva ve ark., optik kayıt uygulamalarında kullanılan, azobenzen içeren düşük moleküler ağırlıklı organik camları çalışmışlar [123], Ouyang ve ark., hidro-termal yöntemle ilk defa grafen/MoS 2 (G/MoS 2 ) kompozitlerini sentezlemişler, sonrasında döküm yöntemiyle organik cam üretmek üzere metil metakrilatı dağıtmışlar ve elde edilen organik camın lineer olmayan absorpsiyon özelliklerini incelemişler [124], Traskovskis ve ark., düşük-moleküler ağırlıklı azobenzen ve stilbenden hareketle 1,1,1 trifenilpentan kriztalizasyonunu kullanarak yeni bir modüler sentetik yaklaşımda bulunmuşlardır [125]. Son dönemde organik fotovoltaiklerin optimizasyonu ve üretiminde önemli ilerlemeler kaydedilmiştir.…”

Poli akrilat, polis stren ve polikarbonat gibi organik polimerlerden ve metil metakrilatlı vinil klorür kopolimerlerinden elde edilen şeffaf, katı malzemelere teknik bağlamda organik cam adı verilmektedir. Endüstride, "organik cam" terimi ile genellikle metil metakrilatın blok polimerizasyonuyla üretilen bir malzeme tabakası anlaşılmaktadır. Organik cam, vakum ya da pnömatik şekillendirme veya baskılanma yöntemleriyle işlenebilmektedir, ayrıca, mekanik sürece tabi tutulabilmekte ve yapıştırılıp kaynaklanabilmektedir. Hava araçlarında, otomobillerde ve gemilerde yapı malzemesi, kış bahçelerinde, pencere ve verandalarda örtücü olarak kullanılmaktadır. Binalar sıklıkla organik camlarla dekore edilmekte ve cihaz parçalarında, protezlerde, lenslerde, optik uygulama pirizmalarında, ayrıca yiyecek endüstrisi borularında değerlendirilmektedir. Bu çalışmada organik camlar tanımlanmakta, türleri, üretimleri ve son dönem çalışmaları sunulmaktadır.
