Influence of Y2O3, Sc2O3 and HfO2 dopants on green emission of Er3+ ions in PbO–Sb2O3 glasses

Influence of nanosized defects on photoluminescence efficiency of Er3+ ions co‐doped with Au2O3 in a lead boroselenate glass ceramic system: a novel approach using positron annihilation lifetime spectroscopy

“…Spectra exhibited the bands due to: absorption transitions of Er 3+ ions in the visible region. [ 3 ] As the Au 2 O 3 content was increased from 0.025 to 0.075 mol%, a considerable growth of these bands was noticed [inset (a) of Figure 9]. It may be noted here that in the absorption region of 500–580 nm, the SPR band due to Au 0 MPs was also detected (by recording the OA spectra of only the gold oxide‐doped glass ceramics with no Er 2 O 3 ).…”

“…[2] By adding PbO, a heavy metal oxide to this glass system, its density and refractive index can be increased further; as a result, the photoluminescence (PL) efficiency of the dopant RE ions is predicted to increase. [3,4] In the present study, we have added a minimal quantity of B 2 O 3 (10 mol%)to facilitate glass formation in the PbO-SeO 2 system.…”

Amplification of blue emission of Tm3+ ions in Li2O‐HfO2‐SiO2 glass system by means of Au0 metallic particles

“…3 H 5 (400-550 nm), the luminescence emission of Hf 4+ ions was also reported earlier. [38] The spectra also indicated the bands corresponding to 3 F 4 ! 3 H 4 , 3 H 4 !…”

Nd3+‐Doped Lead Boro Selenate Glass: A New Efficient System for Near‐Infrared 1.06 μm Laser Emission

“…[ 24 ] Moreover, the vibrational bands of selenate [SeO 4 ] 2− groups and isolated pyramidal selenite [SeO 3 ] 2− groups are also located in these spectra at about 950 cm −1 and in the wavenumber region 850–900 cm −1 , respectively. [ 25 ] Yet, the bending vibrational bands of SeOSe and BOB bondings [ 25,26 ] and the band due to vibrations of SeO bonds of isolated SeO 3 units are also visualized around 705 and 455 cm −1 , respectively; [ 25 ] it may be noted here that in the region of vibrations of SeO 3 units, the vibrational band of PbO bonds of PbO 4 structural units is also predicted. [ 27 ] With the gradual rise of SeO 2 content in the glass matrix, the bands due to quarantined [SeO 3 ] 2− pyramids and BO 3 units are observed to grow (with shifting of the peak positions toward lower wavenumber) while that of vibrational bands of SeO 4 and BO 4 units exhibited a decreasing trend.…”
