Single-crystalline lanthanum hexaboride (LaB6) nanowires show excellent electric-field-induced electron emission following the Fowler–Nordheim scheme. The LaB6 grow in <001> crystallographic direction (see Figure) with diameters of about 20 nm. An current 30 nA from a single nanowire, corresponding to density 5 × 105 A cm–2, has been obtained.
A multi-excitation quartz enhanced photoacoustic spectroscopy (QEPAS) and photothermal integrated detection structure is introduced. laser beam incident at a certain angle obtained by tilting the fiber optic collimator, two plane mirrors are placed on both sides of tuning fork (QTF). This causes to retrace several times between arms QTF. The metal layer in middle bottom QTF removed chemical etching for through QTF, so that can travel back forth achieves multiple excitation single...
A dual-gas intra-cavity quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor based on frequency division multiplexing (FDM) of a quartz tuning fork (QTF) using two acoustic microresonators (AmRs) was demonstrated in this paper. The AmRs were constructed into fiber ring lasers with C-band and L-band erbium-doped fibers (EDFs) pump sources, eliminating the model competition dual-wavelength improving stability wavelength. Two laser beams modulated different frequencies <italic...
LaVO4: Eu3+ phosphors with high purity and crystallinity were successfully prepared by a hydrothermal method the addition of polyvinylpyrrolidone over wide pH range. The mechanism influence on evolution crystal morphology luminescence properties was explored analyzed. Finally, electronic structure optical LaVO4 Eu3+-doped different structures investigated theoretical calculations combined first nature principle. results show that surface samples formed under acidic conditions is rough.
