Niobium pentoxide: a promising surface-enhanced Raman
2017年3月15日 · In this work, a semiconductor based on Nb 2 O 5 is reported as a new candidate for highly sensitive surface-enhanced Raman scattering detection of dye molecules. The largest enhancement factor...
Synthesis, physical, FTIR, and optical characteristics of B
2022年9月26日 · FTIR measurements reflected that relative fraction of BO4 (P4) decreases while relative fraction of BO3 (P3) increases by Nb2O5 doping. Such a result confirmed that the Nb ions cause a variation in borate structural coordination and partially back conversion from [BO4] to [BO3] units in the glass network.
