Abstract

NOVOS FóSFOROS AMARELO-VERDE BASEADOS EM SILICATO São revelados sistemas de fósforo, inovadores, tendo a fórmula A~ ~2SiO~4~:Eu¬ 2+¬D, onde A é pelo menos um de um metal divalente selecionado do grupo consistindo em Sr, Ca, Ba, Mg, Zn, e Cd; e D é um dopante selecionado do grupo consistindo em F, Cl, Br, I, P, S e N. Em uma modalidade, o fósforo inovador tinha a fórmula (Sr~ 1~-x-y~Ba~ x~M~ y~)~ 2~SiO~ 4~:Eu¬ 2+ ¬F(onde M é um de Ca, Mg, Zn, ou Cd em uma quantidade variando de 0<y<0,5). O fósforo é configurado para absorver a luz visível a partir de um LED azul, e luz luminescente a partir do fósforo mais a luz a partir do LED azul podem ser combinadas para formar luz branca. Os fósforos inovadores podem emitir luz, com intensidades superiores as dos compostos YAG convencionalmente conhecidos, ou dos fósforos à base de silicato que não contêm o íon dopante inventivo.
