Effect of carbon on the co-presence of metallic tungsten as a nucleation agent and Eu2+ in glass: crystallization of CaO–Al2O3–SiO2 glass probed with Eu2+ luminescence

“…In addition, composites can compensate for the shortcoming of individual components and make them functional. One example is glassceramics (GCs) [1][2][3][4][5][6][7][8][9] generated by precipitating crystalline phases in glassy phases. GCs were developed because glass bulk materials are brittle materials whose mechanical properties are improved by the precipitation of crystal particles.…”

“…[2][3][4][5][6][7][8][9] These GCs can be obtained by crystallization of glass doped with rare-earth ions such as Eu 3+ , Tb 3+ , and Dy 3+ . [6][7][8][9] Some of GCs exhibit a decrease in the luminescence with increasing crystal eld. [9][10][11] In contrast to these rare-earth ions, Eu 2+ can exhibit an increase in luminescence with increasing crystal fraction, [12][13][14][15][16] which might be advantageous for using spectroscopic imaging.…”

“…[1][2][3][4][5] In the case where the crystal particles exhibit luminescence, the corresponding GCs are considered to be highly promising optical materials. [2][3][4][5][6][7][8][9] These GCs can be obtained by crystallization of glass doped with rare-earth ions such as Eu 3+ , Tb 3+ , and Dy 3+ .

Sol–Gel Photonic Glasses: From Material to Application

“…By engineering the glass-ceramics chemistry, the nature, or volume fractions of crystalline and amorphous phases, several interesting properties related to the RE-doped luminescent nanocrystals (fluorides, chlorides, oxychlorides, etc.) can be achieved and tailored so that the sol–gel technique appears to be one of the most versatile processes for the fabrication of photonic systems [ 105 , 106 , 107 , 108 , 109 ].…”
