“…In recent years rare-earth-doped glasses have been subject of intense research as host materials because of their significant optical properties, which make them adequate as infrared and upconversion lasers, optical amplifiers, and active photonic devices [1][2][3][4][5][6][7][8][9]. In particular, silicate and aluminosilicate glasses present excellent thermal and mechanical properties, and corrosion resistance to be used in practical applications [10][11][12][13][14][15][16][17].…”

“…[1][2][3][4][5][6][7][8] However, most of the studies observed that the nonlinear optical glasses are in general made up of silicate, germinate, chalcogenide and tellurite based glasses doped with metal oxide nanoparticles or rare earth oxides. [1][2][3][4][5][6][7][8] Now, in this work, we explore nonlinear optical properties coupled with dielectric dispersion (polarization) of lithium borate glasses containing two transition metal oxides. Lithium-borate glasses have gained technological importance due to their high transparency for a wide range of wavelengths (200-2500 nm) and low melting point (… 1000 ○ C) compared to that of silicate and germinate glasses.…”

“…Essas nanopartículas de prata, quando presentes em vidros germanatos dopados com íons de Pr 3+ causam aumento significativo da luminescência do referido íon, na região do visível; na sequência, como desdobramento do trabalho vários íons de terras-raras tiveram suas luminescências engrandecidas na presença de nanopartículas de prata e ouro [9,10,11,12]. Guias de onda com estruturas RIB em pedestal apresentaram aumento do ganho na região do infravermelho em função da nucleação de partículas de ouro [13,14,15,16]. Recentemente germanatos dopados com íons de Nd 3+ e NP's de prata indicaram um aumento de 160% na intensidade de fotoluminescência em 1064 nm devido, principalmente, ao aumento do campo local produzido pelas NP's [17] A respeito da matriz TeO2-ZnO, esta foi amplamente estudada pelo grupo e assim como na matriz anterior, os resultados obtidos motivam pesquisa atual.…”

“…Tal fato, assim como na amostra anterior, com NP's de prata, pode ser atribuído ao intenso campo local nas vizinhanças da camada de ouro, que aumenta a densidade de íons Nd 3+ excitados, favorecendo o ganho. Efeito similar foi visto em trabalhos anteriores do grupo para guias de onda com arquiteturas RIB e pedestal[13,15,16,108].…”
