Enhanced infrared to visible upconversion emission in Er3+ doped phosphate glass: Role of silver nanoparticles

Effect of silver nanoparticles on spectroscopic properties of Er3+ doped phosphate glass

“…The primary reason for enhancement in luminescence intensity is the local field induced by SPR of Ag metal NPs [33][34][35][36]. The energy transfer from the metal to rare earth ions is mainly Table 3 Thermal parameters of NPZEA0, NPZEA1 and NPZEA2 glasses.…”

Enhanced luminescence from silver nanoparticles integrated Er3+-doped boro-tellurite glasses: Impact of annealing temperature

“…Sahar et al [14,15] acknowledged the overall luminescence enhancement by attributing to the SPR (major contribution) and ET (minor contribution) mechanism. Other researchers [16,17] argued that the SPR mediated effect as the major factor for enhancement and the ET from Ag to RE ions has insignificant contribution.…”

Investigation of the role of silver species on spectroscopic features of Sm3+-activated sodium–aluminosilicate glasses via Ag+-Na+ ion exchange

“…INTRODUCTION Recently, coupling rare earth ions (REI) with silver nanoparticles (Ag NPs) have been developed as a valuable approach to enhance the luminescence of REI. [1][2][3][4][5][6][7][8] It was first demonstrated in Ref. 1 where Eu 3þ -doped fluoroborate glasses containing Ag NPs were investigated.…”

“…Sequentially, many investigations on enhancement of REI emissions in Ag-REI co-doped glasses were reported. [2][3][4][5][6][7][8][9][10][11][12][13] But some researchers [9][10][11]13 ascribe this enhancement effect to energy transfer (ET) from very small molecule-like, non plasmonic silver particles (ML-Ag) or isolated Ag þ to REI, but not to the LFE induced by SPR. Rademann et al 9 developed a technique to produce molecule-like noble metal particles in soda-lime silicate glasses by synchrotron X-ray activation and ascribe the enhancement effect to ET from ML-Ag to REI.…”
