Este estudio se enfoca en la producción y caracterización de vidrios de aluminato de calcio dopados con Dy3+/Sm3+ para generar luz blanca. Los vidrios se produjeron mediante la técnica de fusión/enfriamiento y mostraron mayor densidad con los dopantes. Los espectros de absorción y luminiscencia mostraron las transiciones de las tierras raras. Con un 0,5% mol de samario en las muestras co-dopadas, la temperatura de color se desplazó de 4002 K a 3433 K bajo excitación a 360 nm, logrando una luz blanca más cálida. Este trabajo demuestra el control de la coloración de la luz emitida.
