Potassium-alumina-boron glass doped with copper ions for solar cell down-convertors

The Effect of Heat Treatment on the Optical Properties of Copper-Containing Lithium-Potassium-Borate Glasses

“…1b). As reported in [15], such a color is typical for the glass containing copper nanoparticles. Thus, Analyzing the data registered for the other glasses, one can conclude that the addition of lithium oxide caused drastic transformation of DSC curves.…”

“…According to Ref. [15], the wide photoluminescence bands in Fig. 3 correspond to the band of monovalent Cu + copper ions.…”

“…Generally, the quantum yield of luminescence related to copper ions in borate glasses can reach 50% [14]. The luminescence excitation in lithiumpotassium-alumina-borate glasses with monovalent copper ions in the glass matrix was reported in [15]. In [16], authors discussed the glass annealing effect on the luminescence of chromium-containing lithium-potassium-alumina-borate glasses; the formation of the luminescent Li(Al 7 B 4 O 17 ) phase with the typical peaks at 685, 700, and 715 nm was stated; the quantum yield here was estimated as being more than 50%.…”

Spark Sensor Based on Lithium-Potassium-Aluminophosphate Borate Glass Doped with Eu

“…In this paper, the design of a device operating in UV range of electromagnetic spectrum is proposed. There are several reports on the use of phosphors in spark sensors [8][9][10][11][12]. However, their design does not imply the use of UV light range only.…”
