In this study, oxyfluoride glasses with chemical composition of 45SiO 2–15Al 2 O 3–10BaO–
30BaF 2-xTbF 3 (x= 0.2, 0.4 and 0.6 (mole ratios)) were prepared through the conventional …

A detailed structural investigation of a series of fluoride phosphate laser glasses with
nominal composition 25BaF2–25SrF2–(30–x) Al (PO3) 3–x AlF3–(20–z) YF3: z REF3 with …

A Ho^ 3+-doped PbF_2 mid-IR laser crystal was successfully grown using the vertical
Bridgman method. An intense 2.8 μm emission in Ho: PbF_2 crystal was observed for the …

The use of Nd^ 3+ codo** for sensitizing the Ho^ 3+ ion and enhancing the∼ 3.9 μm
emission from Ho^ 3+: I_55→ I_65 was investigated in the PbF_2 crystal for the first time, to …

Structure–property correlations in oxyfluoride glasses have been explored in a series of lead
fluoroborate and lead fluorogermanate glasses with nominal compositions (50–x–y–z) B2O3 …

The co-existence of light and heavy rare earth ions will arouse interesting optical, magnetic
and magneto optical properties to matrix due to energy transfer between various rare earth …

We present an original method based on the 31P solid-state NMR relaxation to determine
low concentrations (< 1 at%) of paramagnetic ions in monazite LaPO4 crystals with a high …

A novel Ho^ 3+/Yb^ 3+-codoped PbF_2 mid-IR laser crystal was successfully grown and
analyzed. Enhanced emission at 2.86 μm was observed from the crystal under excitation of …
