“…The observed results confirm previously reported experiments showing the effect of concentration on the optical limiting. 26,27 In order to investigate the dependence of the pH on the optical limiting, solutions at various pH values from 2-9 were prepared from 200 µg/l. Figure 4 shows the results of the output power for BPB at different pH ranging from 2-9 values as a function of incident power at two different wavelength 488 nm and 514 nm.…”

The nonlinear properties and optical limiting performance of Bromophenol indicator solution were investigated using continuous wave laser beam at 488 nm and 514 nm. A z-scan technique was used to measure the nonlinear refractive index. The optical limiting was investigated by monitoring the output transmission through the samples at different concentrations and at different pH values. The results show the dependence of the optical limiting threshold on concentration as well as on the pH values of the solution. The investigation shows that bromophenol blue is a potential candidate for optical limiting. Results also show that the optical limiting values can be used as a pH indicator.

“…It is well known that RSA mechanism leads to absorption increase in the sample with increase in intensity which is also explaining the nonlinear optical limiting action in the organic materials [19][20][21]. Following our recent investigations on optical limiting behavior of acid blue29, under excitation of a low power (CW) He-Ne laser irradiation in ethanol only at four different concentrations [9], this paper shows that both nonlinear refraction and nonlinear absorption change with decreasing of solvents polarity and varying the input powers using a 35 mW HeNe laser radiation at 632.8 nm.…”

The nonlinear optical limiting and relative nonlinear refractive index in far-field of acid blue29 dye are investigated using radiation of 35mW CW He-Ne laser. It is found that both nonlinear refraction and nonlinear absorption change with decreasing of solvents polarity and varying the input powers. 1-IntroductionWith the extensive use of high-power laser in many different applications, much interest is currently being directed towards the search for new nonlinear optical materials for passive optical limiters used to protect human eyes and solid-state optical sensors from intense laser beams [1][2][3]. Over the past decades, extensive studies on optical limiting materials have been focused on nonlinear organic molecules [4][5], organic dyes [6] and conjugated compounds [7] with respect to nanosecond optical limiting behavior. Nonlinear optical properties of organic dye molecules such as a large nonlinearity, broadband spectral response and fast response time are important for realizing the potential for using organic dyes and their applications in optical limiting and processing fields [8]. Several groups were investigated the concentrations effect on the optical limiting behavior of organic dye molecules [9][10][11][12][13][14][15]. But, several studies were focused on the solvent effect on the optical limiting behavior of organic dye molecules [16][17][18]. The nonlinear absorption mechanism in the dyes is due to reverse saturable absorption (RSA), depending on the change in the absorption in relation with intensity increasing. It is well known that RSA mechanism leads to absorption increase in the sample with increase in intensity which is also explaining the nonlinear optical limiting action in the organic materials [19][20][21]. Following our recent investigations on optical limiting behavior of acid blue29, under excitation of a low power (CW) He-Ne laser irradiation in ethanol only at four different concentrations [9], this paper shows that both nonlinear refraction and nonlinear absorption change with decreasing of solvents polarity and varying the input powers using a 35 mW HeNe laser radiation at 632.8 nm.

“…This technique has the advantageous to be applied in existing thin-film coating technologies from inkjet and screen printing for individual substrates to continuous roll-to-roll manufacturing using slot-die coating, gravure printing or doctor-blading [5]. Other than potential Nursaadah Ahmad Poad et al, 2018 applications as flexible displays, RF-ID components and e-papers, the organic semiconducting materials had been explored for photonics, electro-optics and laser materials [6][7]. The material can be fabricated into eyes protection devices and sensors for intense laser beams that is useful in military and weaponary purpose [6].…”

The interface structure between inorganic/organic layer governed microscopic and physical property of many organic based devices. The 1,4,5,8-napthalenetetracarboxylic dianyhride (NTCDA) is strong electron acceptor and its thermal stability can be explored in electro-optics application and laser material. In this study, optical characteristics of NTCDA film at interface of indium tin oxide (ITO) was demonstrated. The film was processed using ethanol and toluene solvents at 1:1 ratio before spin coated on 180 nm thickness ITO substrate. Hexamethyldisilaze (HMDS) was used to surface functionalized the ITO substrate. Analysis of AFM images showed the NTCDA film grown on ITO substrate at grain size approximately 0.5-1.5 m. The onset of the absorption band shifted around 0.11 eV upon HMDS modification at interface of NTCDA film and ITO substrate indicating electronic modification on the bulk NTCDA film. Structural conformation was studied using the infrared absorption. Other than strong absorption peak at 1783 cm-1 that belonged to vibrational mode of the C = O functional group of the NTCDA, the fingerprint peaks of NTCDA on FTIR spectra were present with or without HMDS modification. This study showed the bandgap tuning of organic semiconductor film using surface functionalization technique as potential material processing in defence technology application.
