Structural, optical, and magnetic properties of KBiFe2O5 synthesized by a sol‐gel method using PVP as additive

“…The sol‐gel synthesis is an uncomplicated method to obtain ceramic materials, known for being a simple, fast, environmentally friendly and low‐temperature method for various ceramics and well‐known as a route to obtain thin films 21,22 . In this work, the synthesis of KBFO in the form of powder using a sol‐gel method, at different times and temperatures and using PVP as an additive was investigated.…”

Optical Properties of New Terbium(III) Ternary Complexes Containing Anionic 6,6,7,7,8,8,8‐heptafluoro‐2,2‐dimethyl‐3,5‐octanedione and Neutral Sensitizers in Solution, Solid and PMMA Thin Films: Intra and Interphase Colour Tuning

“…The absorption spectra show excitonic absorption edge at 293 nm, 290 nm, 285 nm and 298 nm for 1 , 2 , 3 and 4 respectively. The corresponding band gap energy ( E g ) for these complexes has been determined using following Einstein’s equations (40) where h is Planck’s constant, c is the velocity of light and is the excitonic absorption edge. The calculated band gap energy for complexes 1 , 2 , 3 and 4 is ~ 4.23 eV, 4.27 eV, 4.35 eV and ~ 4.16 eV respectively.…”
