The effect of plasmonic near field tuning on spontaneous emission intensity of dual emitting ZnO:Er3+ nanoparticles

Modulated Luminescence of Lanthanide Materials by Local Surface Plasmon Resonance Effect

“…In the past decades, these ultrafine particles have been extensively studied by us different fabrication methods of glasses containing ultrafine Ag and Au partic Hayakawa and his co-workers presented the excitation enhancement in the presenc silver particles of 4.3 nm size due to the local field enhancement [40]. Later, many resea ers realized excitation enhancement by the enhancement of local field [41][42][43][44][45][46][47]. Figu shows that the Er 3+ excitation efficiency increased to 70 times when it was excited at nm [41].…”

Optical, Physical and Structural Properties of Er3+ Doped Low‐Phonon Energy Vitreous Matrix: ZnO‐B2O3‐TeO2

“…In recent years, tellurium oxide (TeO 2 ) based glasses have attracted research interest because of their technologically important functional properties . TeO 2 glasses are marked by distinctive physical and optical properties such as high solubility for rare earth ions, low melting temperature (≈750 °C), low glass transition temperature, high refractive indices (≈2.1–2.3), high dielectric constant, excellent transparency in the visible and IR regions (≈400–6000 nm), good mechanical and chemical strength, low phonon energy (600–850 cm −1 ), high thermal stability in comparison to both fluoride and phosphate glasses and less radiative losses . TeO 2 , being a conditional glass former, readily undergoes crystallization due to the presence of lone pair of electrons at the equatorial position of TeO 4 units.…”
