“…Therefore, there must be the existence of energy transfer processes between Er 3+ and Ho 3+ . The phenomenon is also observed in Er 3+ /Ho 3+ co-doped tellurite glasses 15,16 . The inset of Fig.1 plots the dependence of Ho 3+ concentration on fluorescence intensities at 548 nm and 658 nm, respectively.…”

“…An absorption peak centered at 10246 cm -1 (~976 nm) can be observed from absorption spectrum, suggesting that the prepared germanosilicate glasses can be pumped by commercially available 980 nm LD. Based on previous reports [15][16][17] , the energy transfer mechanism between Er 3+ and Ho 3+ is as follows:…”

The energy transfer mechanism between Ho(3+) and Er(3+) ions has been investigated in germanosilicate glass excited by 980 nm laser diode. A rate equation model was developed to demonstrate the energy transfer from Er(3+) to Ho(3+) ions, quantitatively. Energy transfer efficiency from the Er(3+):(4)I13/2 to the Ho(3+):(5)I7 level can reach as high as 75%. Such a high efficiency was attributed to the excellent matching of the host phonon energy with the energy gap between Er(3+):(4)I13/2 and Ho(3+):(5)I7 levels. In addition, the energy transfer microparameter (CDA) from Er(3+):(4)I13/2 to Ho(3+):(5)I7 level was estimated to (4.16 ± 0.03) × 10(-40) cm(6)·s(-1) via the host-assisted spectral overlap function, coinciding with the CDA (2,88 ± 0.04) × 10(-40) cm(6)·s(-1) from decay analysis of the Er(3+):(4)I13/2 level which also indicated hopping migration-assisted energy transfer. Furthermore, the concentration quenching of Ho(3+):(5)I7 → (5)I8 transition was the dipole-dipole interaction in the diffusion-limited regime, and the quenching concentration of Ho(3+) reached 4.13 × 10(20) cm(-3).

“…For WDM, both Er 3+ and Tm 3+ are of high interest because their complementary luminescence which ( 4 I 13/2 → 4 I 15/2 ) centered at 1.53 m for erbium and 3 H 4 → 3 F 4 centered at 1.47 m for thulium could allow for the production of an optical amplifier in both the S and C telecommunication bands [2][3][4].…”

“…For the green emissions, the 4 I 11/2 level is directly excited with 980 nm pumping light by means of ground state absorption and/or by energy transfer (ET) process from 2 F 5/2 level of Yb 3+ . Since the absorption cross section of Yb 3+ in the excitation wavelength region is much larger than that of Er 3+ , the ET process from Yb 3+ to Er 3+ dominates (11). Then the cross-relaxation may occur in the following way (CR): 4 I 11/2 + 4 I 11/2 → 4 F 7/2 + 4 I 15/2 and/or absorption of a photon by ET: 2 F 5/2 + 4 I 11/2 → 2 F 7/2 + 4 F 7/2 from Yb 3+ .…”

Red, green and blue (RGB) emissions related to frequency upconversion and energy transfer process in Er 3+ /Tm 3+ /Yb 3+ doped tellurite glass under 980 nm excitation are reported. The intense blue (480 nm), green (525 and 550 nm) and red (650 nm) emissions are simultaneously observed at room temperature. The blue was originated from the 1 G 4 → 3 H 6 transition of Tm 3+ ; the green (525 and 550 nm), and red (650 nm) upconversion luminescences were identified from the 2 H 11/2 → 4 I 15/2 , 4 S 3/2 → 4 I 15/2 and 4 F 9/2 → 4 I 15/2 , transitions of Er 3+ respectively. Different concentrations of Tm 2 O 3 and Yb 2 O 3 were used in order to see the influence on the RGB upconversion properties. The intense red, green and blue upconversion luminescence of these glasses might provide the development of potential three-dimensional displays.
