and the OLED-active area was manually aligned to be located within the grating region of the organic laser, with the longer axis of the OLED aligned perpendicular to the grating grooves (Fig.1c). A glue gun (BOSCH, PKP 18E) was used to fix the alignment of the...
where q is laser energy density, the unit is J/mm2, W is laser power, H is laser spot diameter, and v is scanning speed. Laser energy density plays a decisive role in SLS forming, and its size is related to laser power, scanning speed, and scanning spacing [27]. To obtain the sui...
MM25005, Quantel Laser, France) with wavelengths of 808 nm and 915 nm (Fig.2c), pulse widths of 27 ns, pulse repetition rate of 1 to 3 kHz and pulse energies of 140 μJ and 110 μJ, respectively. Each laser has 20 emitters with a total length of 5 mm ...
Morphological and trace elemental analysis were performed with Scanning Electron Microscopy with Field Emission Gun (FEG-SEM - Tescan MIRA3) equipped with Energy Dispersive Spectrometer (EDS - MAX50 from Oxford). Philips X'Pert MRD X-ray diffractometer (XRD - X'Pert PRO PANanalytical), with grap...
10 min. The UV illumination was carried out using a mercury lamp with its main line at 253.6 nm. Additional details on the DPN formation can be found elsewhere28. The SEM images of the Ag DPNs were obtained using a field emission gun electron microscope, namely, Philips XL30 ...

The surface chemical composition of selected samples was determined using X-ray photoelectron spectroscopy (XPS) with a Thermo Fisher Scientific Theta Probe equipped with a monochromatic Al Kα X-ray source (hν = 1486.6 eV) and Ar + ion gun. During the measurements, the pressure inside the ...
From area scans of 0.531 mm2 on several written structures, we find typical root-mean- square roughness of 5 nm, well below the wavelength of the photonic circuits in the telecoms C-band. Measurement set-up In order to characterize the fabricated devices, transmission measure- ments at near-...
After finding the ideal parameters for the piercing process, to evaluate its functionality, a test pattern to be cut consisting on a rectangular piece of 25 × 30 mm2 with rounding corners (radius 4 mm) was chosen. The selection of infrared or visible signal in the monitorization for each ...
Moreover, for the thinner support wall thickness, an improvement in the hardness value of the fabricated samples was observed. This study urges a reconsideration of the common approach of selecting supports for additive manufacturing of samples when a higher quality of the as-fabricated parts is ...
