In this work we use lanthanide based NaYF4:Er3+, Yb3+upconversion nanoparticles (UCNP) to detect ppb-level sensitibity of a xanthene dye, Rhodamine B (RB) dye, under NIR excitation. A static energy transfer was observed between the luminescent UCNP e

The stochastic dynamics of individual co-doped Er:Yb upconversion nanoparticles (UCNP) were investigated from experiments and simulations. TheUCNPwere characterized by high-resolution scanning electron microscopy, dynamic light scattering, and zeta p

A luminescent hybrid organic-inorganic material was synthesized with the sol-gel technique by hydrolysis of tetraethoxysilane (TEOS) and an organic precursor obtained through the esterification of oda (oxydiacetic acid) and EG (ethyleneglycol) in aci

In this work we use the sol–gel technique to develop different luminescent Eu(III) porous materials from a bis(trialkoxysilyl) organic precursor synthesized from the amide of the DPA (2,6-pyridinedicarboxylic acid) with APTES (aminopropyltriethoxys
