Abstract

MATERIAL LUMINESCENTE. A invenção refere-se a materiais luminescentes para excitação de luz ultravioleta ou luz visível contendo compostos quimicos dopados com chumbo e/ou cobre. O material luminescente compreende um ou mais dos compostos tipos aluminato, silicatos, antimoniatos, germanatos e/ou silicatos-germanatos e/ou fosfatos. Conseqúentemente, a presente invenção é uma boa possibilidade para substituir ions alcalinos de terra rara por chumbo e cobre para mudar as bandas de emissão para comprimento de ondas mais longas ou mais curtas, respectivamente. Fornecem-se compostos luminescentes contendo cobre e/ou chumbo com propriedades luminescentes melhoradas e também com melhor estabilidade com relação à água, umidade além de outros solventes polares. A presente invenção tem por objetivo fornecer compostos luminescentes dopados com chumbo e/ou cobre, que tenham uma elevada faixa de temperatura de cor de aproximadamente 2.000 K a 8.000K ou 10.000 K e IRC acima de 90.
