“…A large variety of glasses have been developed with luminescent centers in the form of molecular clusters (MCs) of silver, [13][14][15][16][17][18][19][20] MCs of copper compounds, [21][22][23][24] and MCs and quantum dots of cadmium and lead chalcogenides. [25][26][27][28] Silicate glasses with neutral silver MCs were chosen from this variety for this paper, since they are optimal in the following parameters: High chemical stability of the glass matrix, high (20-60%) quantum yield 29 of the luminescence of the silver MCs, and spectral coincidence of the luminescence band of the silver MCs with the spectral-sensitivity band of silicon photodiodes.…”
