“…In addition, it also may produce local heat, and the irradiated light may not be uniform . Thus, the light of the LEDs requires additional processing to ensure uniformity, such as the addition of a diffusion sheet . In the literature, there have been numerous reports that different biochemical effects can be expected according to variation of the wavelength; therefore, selective wavelengths need to be produced .…”

Photobiomodulation (PBM) is a safe and noninvasive method that can provide various clinical effects. However, conventional PBM devices using point light sources, such as light‐emitting diodes and lasers have various disadvantages, such as low flexibility, relatively heavy weight, and nonuniform effects. This paper presents a novel wearable PBM patch using a flexible red‐wavelength organic light‐emitting diode (OLED) surface light source, which can be attached to the human body as a personalized PBM platform. The palm‐sized wearable PBM patch can be very light (0.82 g) and thin (676 µm). It also has a reasonable operation life (>300 h), flexibility (20 mm bending radius), and low‐temperature operation (<40 °C), and it can provide wide and safe application irrespective of location and time. Fibroblasts, a major type of dermal cells, play a key role in the wound healing process. The results show that OLEDs may have excellent in vitro wound healing effects because they effectively stimulate fibroblast proliferation (over 58% of control) and enhance fibroblast migration (over 46% of control) under various conditions. For maximum effect, peak wavelength control is necessary to optimize cell proliferation and enhance in vivo wound healing effects.

“…As mentioned, the k was negligible at long wavelengths, and the incident light can be significantly absorbed and reflected at the relatively short wavelength due to the drastic increase in the k. Meanwhile, the reflectance of PLZT thin films gradually increased as a function of the deposition temperatures, as shown in Figure 5c, resulting in a 35% increase in the average reflectance value from 17% to 23%, as shown in Figure 5d. The inset of Figure 5d depicts the scheme of the light attenuation of PLZT thin films, and the increased reflectance can be mainly attributed to the decrease of light dissipation from surface scattering as a function of the surface roughness [39]. Commonly, the fringe can appear in the reflectance spectra for the epitaxial thin film due to the interference oscillation resulted from the phase retardation between the reflected light beams at the film-substrate interface and those at the film surface [40].…”

Ferroelectric thin films have been utilized in a wide range of electronic and optical applications, in which their morphologies and properties can be inherently tuned by a qualitative control during growth. In this work, we demonstrate the evolution of the Pb0.865La0.09(Zr0.65Ti0.35)O3 (PLZT) thin films on MgO (200) with high uniformity and optimized optical property via the controls of the deposition temperatures and oxygen pressures. The perovskite phase can only be obtained at the deposition temperature above 700 °C and oxygen pressure over 50 Pa due to the improved crystallinity. Meanwhile, the surface morphologies gradually become smooth and compact owing to spontaneously increased nucleation sites with the elevated temperatures, and the crystallization of PLZT thin films also sensitively respond to the oxygen vacancies with the variation of oxygen pressures. Correspondingly, the refractive indices gradually develop with variations of the deposition temperatures and oxygen pressures resulted from the various slight loss, and the extinction coefficient for each sample is similarly near to zero due to the relatively smooth morphology. The resulting PLZT thin films exhibit the ferroelectricity, and the dielectric constant sensitively varies as a function of electric filed, which can be potentially applied in the electronic and optical applications.

“…Also, the reactive ion etching is a slow etching process in a vacuum chamber using a greenhouse gas CF4 [2]. A glare reducing film usually has low pencil hardness [3] inherited from the polyethylene terephthalate (PET) film, and needs a lamination process to laminate the film to the glass surface. Sol-gel anti-glare coating usually needs high curing temperature [4,5], and most of the time has low pencil hardness [6] because of the high porosity of the sol-gel derived coatings.…”
