Study of the morphological, structural and photophysical properties of dual emission europium-doped ZIF-8 particles

Enhanced removal performance and evaluative interaction mechanism of europium from an aqueous medium by microbial yeast-decorated zeolitic imidazolate framework hybrids

“…19 The peak at 425 cm −1 was assigned to the functional group of Zn–N originating from the chemical reaction between Zn(NO 3 ) 2 ·6H 2 O and 2-methylimidazole. 20,21 Besides, the characteristic peaks of ZIF-8/yeast hybrids were basically consistent with ZIF-8, which indicated that ZIF-8/yeast hybrids were successfully synthesized.…”

Plate-like CDots/EuBDC nanocomposite for ratiometric luminescence thermometry

“…Fig. S7 (ESI†) shows the spectral composition for EuBDC and CDots/EuBDC obtained by: %SC i = 100 x ( A i / A t ), 45 where A i is obtained by the area under the emission spectra in the 400–560 nm and 560–710 nm ranges (see Fig. 6B), and A t is the total area of the spectra.…”

“…The degree of crystallinity was calculated from XRD patterns using eqn (1), where A c is the area under each crystalline peak with index i and A t is the total area under the diffractogram. 44,45 …”

Sensitive luminescent chemosensing of fluoride based on Eu-doped Zn-LMOF in aqueous media: structural and spectroscopic studies

“…[25][26][27][28] The doping of Zn-MOFs derivatives with lanthanides, in particular with Eu(III) ions, improves the emission properties owing to the antenna effect, in which the excitation with UV radiation is absorbed by the π-conjugated organic linker and transferred from the triplet state (intersystem crossing S 1 → T 1 ) to the Eu(III) doping ions, frequently with a red/pink-color emission in the microsecond range. 16,[29][30][31][32] These Eu-doped Zn-MOF-based composites have spawned a new subclass of color-emitting phosphors with applications in OLEDs 29,30,33,34 and optical sensing of nitrobenzene-based explosives, 32,35 metal ions, 36,37 UV radiation, 38 temperature, 39 and O 2 . 40 However, direct anion sensing still remains largely unexplored.…”
