“…The KY3F samples were obtained in the same system by slow cooling. Mixtures of KF-LnF 3 were contained in a cylindrical platinum boat and melted around 990°C and cooled with a rate of ~10 o C/h. The synthesized material had always transparent crystalline regions from which the samples were extracted.…”

“…Большая часть работ по ФЛ (cм., например, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]) относится к проявлениям этих эффектов в системах примесных редкоземельных ионов (РЗИ). Вместе с тем эффекты типа ФЛ могут быть использованы для быстрых оптических переклю-чений твердотельных материалов между состояниями с различными оптическими и электрическими свойствами.…”

“…Além disso, o KY 3 F 10 é um cristal isotrópico, transparente na região do espectro eletromagnético que vai do infravermelho (920 cm -1 ) ao ultravioleta longínquo (~140 nm), tem boa condutividade térmica, boas propriedades termomecânicas, alto limiar de dano óptico (1,5 J/cm 2 , para pulsos com largura temporal da ordem de femtossegundos) e baixa energia de fônon óptico (~400 cm -1 ) [39]. Estudos anteriores mostraram que este cristal pode ser crescido tanto em grandes dimensões pelo método de Bridgman-Stockbarger [40,41,42,43,44] e Czochralski [45,46] quanto na forma de fibras [47,48,4], além de ter sido obtido também pelo método do fluxo [49]. A Figura 1-4 ilustra de forma esquemática como o nível 4f de um íon sofre desdobramentos devido a: 1) repulsão coulombiana entre elétrons dentro do íon 2) interação spin-órbita e 3) influência do campo cristalino.…”
