A novel Nd 3+ ‐doped MgO‐Al 2 O 3 ‐SiO 2 ‐based transparent glass‐ceramics: Toward excellent fluorescence properties
Generally, glass‐ceramics have superior properties compared to their parent glasses. Here, we prepared a novel Nd 3+ ‐doped MgO‐Al 2 O 3 ‐SiO 2 ‐based transparent glass‐ceramics with excellent fluorescence properties. The effects of Nd 2 O 3 content on the structure and properties of glass‐ceramics...

Zusammenfassung: | Generally, glass‐ceramics have superior properties compared to their parent glasses. Here, we prepared a novel Nd
3+
‐doped MgO‐Al

O

‐SiO

‐based transparent glass‐ceramics with excellent fluorescence properties. The effects of Nd

O

content on the structure and properties of glass‐ceramics were studied, aiming to provide a key guidance for preparing this transparent glass‐ceramics. The results revealed that the glass stability increased originally and then decreased with increasing Nd

O
3
content, so did the variation of wavenumbers in infrared spectra. And these glass‐ceramics are mainly composed of cordierite with residual glassy phase. The three phenomenological intensity parameters (Ω
2,4,6
) and radiative properties were estimated by Judd‐Ofelt theory, and the values of Ω

first decreased and then increased with increasing Nd

content. Three main emission peaks ascribed to the transitions from

nm were observed, respectively. The branching ratios for

transition increased as the Nd

O

content raised, and the fluorescence lifetimes of the

F

level were found to increase first and then decrease with Nd

O

content (from 181 to 726 μs). The excellent fluorescence properties indicate that this novel glass‐ceramics can be used as a potential solid‐state optical functional material for 1.06 μm laser emission. |
