Thermal stability and spectroscopic properties of Er3+-doped lead fluorogermanate glasses

Synthesis and infrared spectroscopic properties of Tm3+-doped phosphate glasses

“…The difference between these two temperatures ( T) is related to the thermal stability of the glass. Here T = 130 • C which is a value comparable to that observed for glasses proposed for waveguides applications and integrated optics [12][13][14].…”

Spectroscopic properties of Yb3+ and Er3+ ions in heavy metal glasses

“…The relatively long-lived near-infrared luminescence with the 4 I 13/2 lifetime of 3.24 ms was detected for our lead germanate glass doubly doped with Yb 3+ and Er 3+ , which is about one magnitude of order higher in comparison to lead borate glass. The lifetime is consistent with the values ( = 3.5-4.0 ms) measured for PbO-GeO 2 -Nb 2 O 5 glasses [28], but smaller than for the oxyfluoride lead germanate glass systems [16,29].…”

Infrared-to-red upconversion luminescence in samarium-doped antimony glasses

“…[5][6][7][8][9][10][11][12][13][14]. Triply ionized Er 3+ , Ho 3+ , Tm 3+ , Nd 3+ ions of the lanthanide series have been most widely studied for upconversion processes in various glass hosts [15][16][17][18][19][20]. The trivalent samarium ion (Sm 3+ ) is one of the most important active ions in the RE family (cerium to lutetium) due to its convenient closely lying energy level structure [21], that has been exploited in upconversion processes mainly in low phonon crystalline hosts and rarely in glasses [22][23][24][25][26].…”
