“…Figure 7(a) shows the transmittance of PP film before and after exposure, where there is a decrease in UV–VIS range, because the silicon oxide bond introduces a stronger absorption after exposure, 50 and the formed SiOx layer on top is nanoporous, which introduces a stronger diffuse reflection 51 . The reinforcements of red, green, blue, and yellow dyes conserve transmittance in at 650 nm for red, 550 nm for green, 450 nm for blue, and 570 nm for yellow as shown in Figure 7(b–e), which are in consistent with other reports on dye color filters on glass and PMMA in Table S1 19–22,26,52 . The transmittance values decrease by 10%–20% at these wavelengths after exposure, because the formation of SiO x layer introduces an absorption in UV–VIS range 50 .…”

Color filters and conductive films are widely used in spacecraft, while the lack of lightweight, flexibility, and atomic oxygen (AO) durability confine their potential applications in low earth orbit. In this study, a clear poly(amic acid) with an empirical 20 wt% polyhedral oligomeric silsesquioxane (POSS) solid content is designed for transparency and AO durability. Red, green, blue, and yellow dyes are reinforced with small amounts of 1–5 wt% in POSS polyimides for color filters. A silver nanowire network film is infiltrated onto the POSS polyimide for conductive film. Erosion depth upon hyperthermal AO exposure, surface morphology, surface chemistry, optical transparency, and conductivity have been systematically investigated. The erosion yields of all 20 wt% POSS polyimides decrease by an order of magnitude when subjected to 2.32 ± 0.05 and 2.39 ± 0.06 × 1020 atoms cm−2 AO fluences, as passivating SiOx networks are formed on film surface. The small‐amount dye additives into polyimides do not introduce obvious changes in AO durability and surface chemistry. The silver nanowire infiltrated POSS polyimide film shows a 65.7% transmittance at 550 nm and a sheet resistance of 8.50 ± 0.36 Ohm square−1. This study reveals promising attempts of POSS‐polyimide‐based color filters and flexible conductive films for potential space applications.

“…18 In addition, the hardness of the crystal hosts may be reinforced in the cases of xylenol orange doped KDP 20 and amaranth doped tris-thiourea zinc(II) sulfate (ZTS). 21 Moreover, an increased threshold to laser damage was found in Congo red doped KDP 22 and methylene blue doped L-arginine phosphate, 23 and enhanced thermal stability was investigated when sunset yellow was doped in KDP, 24 and methyl violet was incorporated in ZTS. 25 According to the literature, those improvements endowed by dye-incorporation were generated due to the crystal vacancies filled by dyes, which resulted in reduced defects and the optimized crystal structure, 14,18 the introduction of additional optical and electronic properties from dyes, 16 and the interaction between doped dye molecules and crystal hosts.…”

Inclusion of dyes is efficient for regulating the performance of nonlinear optical (NLO) crystals. The commonly seen anisotropic dyeing of solution-grown crystals, promoted by specific dye−facet interactions, limits their optical applicability. Here, two classic dyes, methylene blue (MLB) and aniline blue (ALB), are each isotropic occluded within single crystals of the widely used NLO material, potassium dihydrogen phosphate (KDP). MLB and ALB, which only partially stain solution-grown KDP crystals, are incorporated isotropically into gel-grown crystals with unspoiled single-crystalline lattices. During the gel crystallization, dye molecules bind to the gelnetworks, and both become incorporated into the crystals, leading to efficient isotropic dyeing. Furthermore, enrichment of dye molecules from gels into crystals is achieved in the case of ALB because the ALB molecules bind strongly and accumulate onto the gel-networks. Hence, this work provides a generally applicable strategy to facilitate the isotropic dyeing of single crystals and further optimization of crystal properties.

“…Thermogravimetric and differential thermal analyses (TG-DTA) are two useful practices for explaining the physical changes that occur in materials as temperature changes. [7] TGA usually explains weight loss in relation to temperature change, whereas energy change in the sample is generally addressed by DTA. The heat capacity of the sample has no effect on the area beneath a DTA peak, which is proportional to the enthalpy change.…”

“…[6] Because of their minimal scattering, good thermal conductivity, and anisotropic nature, single crystals can overcome the challenges that conventional liquid and polymer-built laser gain media face, and thus can be used for SSDLs. [7,8] Nowadays, dye inclusion in crystals has proven to be a more effective way of improving crystal properties. Numerous studies on TGS crystals doped with xylenol orange, amaranth, sunset yellow, and crystal violet dyes have been reported.…”

“…Numerous studies on TGS crystals doped with xylenol orange, amaranth, sunset yellow, and crystal violet dyes have been reported. [7][8][9][10] Xylenol orange dye had been used to improve the properties of various organic and inorganic crystals, such as ammonium dihydrogen phosphate (ADP), potassium dihydrogen phosphate (KDP), L-alanine, thiourea and benzophenone. [1,[11][12][13][14] During our extensive research review, we discovered that colored crystals have richer specific properties than their host uncolored crystals.…”

A positive change in crystal can be induced by dye. Pure and Acid Red 1 dye (AR) doped triglycine acetate (TGAc) single crystals are synthesized by solution approach to enrich the characteristics of pure TGAc crystals. The crystalline nature of the grown crystals is investigated using powder X-ray diffraction. The Scherrer method has been used to calculate the crystallite size of both developed crystals and is compared to the Williamson and Hall method. Fourier transform infrared spectroscopy confirms the existence of several functional groups as well as dye inclusion in the produced crystals. Four distinct absorption bands are found in UV-vis-NIR absorption spectra at the location where AR dye is inserted into the TGAc matrix. Different optical constants, such as optical bandgap (E g ), extinction coefficient (k), refractive index (n) and optical conductivity (𝝈) are measured for both samples based on transmittance measurements. The thermal stability and decomposition temperature of 0.05 mol% AR dye doped TGAc are found to be higher. The doped crystals' improved optical characteristics and thermal stability prove their applicability for optoelectronic applications.
