The pechini method
WebbEr-doped yttrium aluminosilicate nanopowders were synthesized by Pechini method. • Ethanol and water were used as solvent during the resin preparation. • 1.54 μm emission of Er 3+ ion (I max) depends on SiO 2 content, temperature and solvent. • Crystallinity, secondary phases, phonon energy, lifetime, up-conversion affect I max. • WebbThese were synthesized via a Pechini sol-gel method, as verified by powder x-ray diffraction and laser ablation-inductively coupled plasma-mass …
