“…Most of the observed vibration modes are in good agreement with the theoretical ones of the BaZnP 2 O 7 . As has been reported in the literature, 30–33 the peaks in the region 130–300 cm −1 can be attributed to the external modes, such as the lattice modes, whereas the internal modes of P 2 O 7 4− can be designated as the characteristic mode of the PO 3 and P–O–P groups. The symmetric stretching vibrations of the PO 3 lead to the formation of the most intense peaks at ∼1049 cm −1 in the Raman spectra of the as‐sintered BaZnP 2− x Nb x O 7 ceramics.…”

The BaZnP 2−x Nb x O 7 microwave dielectric ceramics were prepared by solidstate reaction method to investigate the impact of Nb 5+ on the composition, microstructure, and vibrational properties, as well as sintering characteristics and microwave dielectric properties. The solubility of Nb 5+ in the BaZnP 2−x Nb x O 7 lattice was limited. A moderate amount of Nb 5+ substitution could promote the densification process. The vibrational characteristics of the BaZnP 2 O 7 ceramics were first studied by performing experimental and theoretical Raman and infrared spectroscopy measurements in this work, and their relationship with the microwave dielectric properties was studied. The acquired results showed that (I) ε r was influenced by both the density and the second phase; (II) the density and full width at half maximum of the Raman vibrational peak played a critical role in affecting the Q × f values. The BaZnP 2−x Nb x O 7 samples sintered at 925 • C exhibited the outstanding microwave dielectric properties with x = 0.02: ε r = 7.98, Q × f = 60 615 GHz (tan δ = 2.18 × 10 −4 ; f = 13.21 GHz) and τ f = −52.93 ppm/ • C (ρ bulk = 4.03 g/cm 3 ; ρ r = 92.69%). The proposed ceramic is expected to be used in microwave substrates.

“…As a copper phosphate compound, copper pyrophosphate used to be a raw material for the preparation of copper plating solutions in the industry . Due to the metal pyrophosphate group, i6t shows broad application prospects in the fields of advanced energy storage devices, , magnetic devices, , photoluminescence, dielectric devices, catalysis, photocatalytic, and electrocatalysis. , Inspired by this, we mixed and blended copper pyrophosphate with acrylonitrile–butadiene–styrene (ABS) copolymer to prepare the ABS/Cu 2 P 2 O 7 composites as a LISM material. After NIR and UV laser activation and ECP, excellent 2D and 3D copper patterns (or circuits) were successfully obtained at the laser-activated area of the ABS/Cu 2 P 2 O 7 composite.…”

Laser-induced selective metallization (LISM) technologies have received much attention because of their applications in metallized patterns and two-dimensional (2D) and threedimensional (3D) circuits. Our work proposed a new laser sensitizer, copper pyrophosphate (Cu 2 P 2 O 7 •3H 2 O), which can perform LISM for both 1064 nm near-infrared (NIR) laser and 355 nm ultraviolet (UV) laser. Conductivities of copper layers obtained by NIR and UV LISM on the ABS/Cu 2 P 2 O 7 composite were 1.52 × 10 7 and 1.47 × 10 7 Ω −1 •m −1 , respectively. The copper layer adhesion to composites reached the 5B Level of ASTM D3359. Thermal gravimetric analysis (TGA) and X-ray diffraction (XRD) revealed that Cu 2 P 2 O 7 •3H 2 O changed color due to the loss of crystalline water during composite preparation. Scanning electron microscopy (SEM), optical microscopy (OM), and Raman imaging indicated that a microrough structure and amorphous carbon appeared on composites. X-ray photoelectron spectroscopy (XPS) revealed that Cu 2 P 2 O 7 •3H 2 O was reduced to Cu 0 after laser activation, and this Cu 0 was the active species to induce electroless copper plating (ECP). About 54.39 and 30.57% of Cu 2+ were reduced to Cu 0 after NIR and UV laser activation. NIR laser can generate more Cu 0 due to a higher thermal effect, so the speed of ECP is faster. In addition, decorative patterns and interdigitated capacitor patterns were successfully fabricated on 3D plastic parts by LISM, demonstrating potential application prospects.
