Tunable photoluminescence of porous silicon by liquid crystal infiltration

Effects of Sintering Temperature on the Morphology and Photoluminescence of Eu3+ Doped Zinc Molybdenum Oxide Hydrate

“…Color coordinates are important parameters to quantitatively describe the emission color for luminescent materials, and the CIE chromaticity coordinates can be calculated from the PL spectral data of luminescent materials [17][18][19][20]. the Eu 3+ doped ZMO at 600 ∘ C for 2 h. As can be seen in Figure 7, the X-ray emission peaks are located at 0.53, 1.02, 2.30, 8.61, and 9.57 keV, corresponding to the characteristic X-ray emissions of O(…”

On alignment of nematic liquid crystals infiltrating chiral sculptured thin films

“…The tuning of inverted opals, which are photonic crystals with backbones made of dielectric materials with high refractive indices and can be as much as 75% porous, was demonstrated a decade ago [2] by infiltrating them with nematic LCs. The similar infiltration of III-V semiconductor slab waveguides has also been accomplished [3,4], as also of a host of photonic crystals [5][6][7][8][9][10][11][12][13].…”

Tuning photoluminescence of liquid crystals doped ZnS nanoflakes

“…Weller and co-workers reported earlier about the fabrication of CdSe/ZnS core-shell nanoparticles with high reaction yields with the PL quantum efficiency of 50-60% [16]. Recently, liquid crystals (LC) have been used to modify the physical properties of nanomaterials [17][18][19][20]. LC is to be considered to apply their own effect on the modification of physical properties of nanomaterials.…”
