Diode pumped white light emission from dysprosium and samarium doped glasses

Glasses embedded with Dysprosium and Samarium were made by the melt quenching technique. Dy 3+ -doped glasses exhibited bright white luminescence under 10 mW of 405 nm diode laser excitation. Color rending index of the glass was improved by adding Sm 3+ as a co-dopant to the glass. Spectroscopic results of the glasses are discussed.
