Interestingly, intense characteristic emissions are observed at the near-infrared regions (800 to 1,400 nm).
Besides, SnO2/SiO2-GSH NSs show an intense characteristic peak of amorphous silica around 23° (JCPDS card no.
The UV vis spectrum of PPD (Figure 5) shows three narrow and intense characteristic absorption bands centered at 199, 237, and 299 nm.
Venice turpentine turns out to be softer and more malleable than other resins and retains the intense characteristic odor of the original resin.
In the saponified SAP, the very intense characteristic band at 1,562 cm−1 is due to C=O asymmetric stretching in the carboxylate anion.
Upon ultraviolet (UV) or near infrared (NIR) excitation, the as-synthesized NaLa(MoO4 2 Ln3+ phosphors exhibit intense characteristic down-conversion or up-conversion luminescence, respectively.
The increase in crystallinity in the films was observed as a function substrate temperature, and for the films deposited at Ts = 473 K, the respective X-ray diffractogram exhibited relative broad and high intense characteristic diffraction peak at 2θ = 20.3°, which attributed to Bragg reflection from (001) lattice planes of orthorhombic V2O5.
The FTIR spectroscopic analysis of the biomass, microalga I. galbana before adsorption of chromium metal ions (Fig. 7) showed several intense characteristic bands, which can be attributed to functional groups present in the protein and polysaccharides such as carboxylic, CH2, NH and –OH groups.
For the as-prepared sample without solvent extraction, intense characteristic absorption bands associated with C-H bond (about 1,500 and 3,000 cm-1) are evident for the presence of the organic surfactant, which almost disappeared for the spectrum of Co-SiO2.
The as-synthesized BaMoO4 Ln3+ (Ln = Eu, Tb, Dy, and Sm) phosphors show intense characteristic red, green, green yellow, and orange red emissions under ultraviolet light excitation, which might find potential applications in the fields of light emitting phosphors, advanced flat panel displays, and light-emitting diodes (LEDs).
