Spectrofluorimetric quantification of bromazepam using a highly selective optical probe based on Eu3+–bromazepam complex in pharmaceutical and serum samples

Spectrofluorometric Determination of Alpha Fetoprotein in different serum samples of Liver Cancer by Tb-acetyl acetone complex embedded in Polymethylmethacrylate optical sensor

“…After the addition of ACAC to the Tb 3+ ion in the PMMA matrix, the characteristic peaks of the Tb 3+ ion ( 5 D 4 → 7 F 6 , 5 D 4 → 7 F 5 , and 5 D 4 →F 4 ) appeared (see curves 2 and 1 in Fig. 2) [27][28][29][30][31]. Comparing curve 4 with curves 2 and 3 in Fig.…”

Spectrofluorimetric Assessment of Hydrochlorothiazide Using Optical Sensor Nano-Composite Terbium Ion Doped in Sol-Gel Matrix

“…6 H 2 O in sol-gel matrix was studied under the conditions established above. The results show that there is no quenching in the energy of Tb 3+ -(HCT) in solgel matrix in the presence of acetonitrile [30][31][32][33][39][40][41][42].…”

A highly luminescent complexes of Eu(III) and Tb(III) with norfloxacin and gatifloxacin doped in sol–gel matrix: A comparable approach of using silica doped Tb(III) and Eu(III) as optical sensor

“…The high luminescence intensity of the Eu 3 þ -NFLX or GFLX and Tb 3 þ -NFLX OR GFLX solutions were observed in aprotic solvents like acetonitrile and DMF. This may be attributed to the formation of anhydrous solvates of the Eu 3 þ -NFLX/GFLX or Tb 3 þ -NFLX/GFLX complexes introducing solvent molecules in the first coordination sphere leading to the enhancement of the intensity of the transition states, especially 5 D 0 -7 F 2 ¼617 and 5 D 4 -7 F 5 ¼545 transitions of the Eu 3 þ and Tb 3 þ [33,34]. Also, the luminescence intensities for the complex in aprotic solvent like acetonitrile and DMF are stronger than in protic solvent like water and ethanol.…”
