“…There is a large variety of patterns that can be observed under different conditions of humidity and temperature. [1,23]. In particular, in specific humidity conditions (relative humidity RH ≈ 30 − 40%) and at room temperature [23], one can observe "maltese-cross"-like patterns when viewing the sample between crossed polarizers and under white light illumination (see Fig.…”

Some anisotropic materials form semicristalline structures, called spherulites, which observed in a polarisation microscope, exhibit a characteristic "maltese-cross"-like pattern. While this observation has been hitherto considered as a tool to characterize these materials, we show that these patterns are associated with a strong light's spin-orbit coupling induced by the spherulite structures. We experimentally demonstrate these effects using samples of crystallized ascorbic acid and observing the creation of optical vortices in transmitted laser beams, as well as the formation of inhomogeneous polarisation patterns. Our findings suggest the use of spherulites in frequency ranges, e.g. in the THz domain, where polarisation and spatial shaping of electromagnetic radiation is still a challenging task.

“…On the sample, the spherulite structures formed around point defects from residual powder grains, either accidentally present from undissolved powder grains in the solution or introduced manually after evaporation. [20,22,23]. There is a large variety of patterns that can be observed under different conditions of humidity and temperature.…”

“…For concentric ring pattern formation in crystal growth of ascorbic acid from its thin solution film, there have been several experimental studies (from methanol solution [12,13,14,15,16] and from aqueous solution [17,18]). The findings in these experimental studies are summarized as follows.…”

“…These findings are common in both cases of methanol and aqueous solutions. So far, we have obtained the two morphology diagrams, which are (i) a function of humidity and the average area density ρ [16], and (ii) a function of humidity and temperature [18].…”

Dynamical Properties in Uniform and Periodic Growth Modes of Ascorbic Acid Crystal Domain from Thin Solution Film

There exists the threshold-sensitive dynamical transition between the uniform and the periodic growth modes in the domain growth of ascorbic acid crystals from its aqueous supersaturated solution film. The crystal growth induces the solution flow. Humidity controls the fluidity of the solution. The solution flow varies the film thickness. The threshold exists in the thickness of the solution film, and the crystal growth almost stops if the thickness becomes lower than the threshold.
