在Na_2 O-CaO-SiO_2（NCS）系统中成功地制备了Nd ~（3+）和Yb ~（3+）掺杂的玻璃和高结晶透明微晶玻璃。与Nd 3+掺杂的NCS玻璃相比，Yb 3+掺杂的NCS玻璃具有更强的析晶趋势。Nd ~（3+）和Yb ~（3+）掺杂的NCS微晶玻璃中Na_6Ca_3Si_6 O_（18）和Na_4Ca_4Si_6 O_（18）的含量分别为84.35±5 vol%和87.03±5 vol%。这两种晶相具有相同的基本结构单元，由6个[SiO 4]基团形成的6元环组成，但Yb 3+掺杂的NCS微晶玻璃中的相具有与其母体玻璃更相似的组成比。Yb ~（3+）掺杂的NCS微晶玻璃的透过率高于Nd ~（3+）掺杂的样品。Nd ~（3+）和Yb ~（3+）掺杂的NCS微晶玻璃具有较强的荧光发射，表明稀土离子掺杂的高结晶度透明微晶玻璃具有作为激光介质材料的潜力。
Nd3+- and Yb3+-doped glasses and highly crystalline transparent glass-ceramics in the Na2O–CaO–SiO2(NCS) system have been successfully prepared. Compared with Nd3+-doped NCS glass, the Yb3+-doped NCS glass has a stronger crystallization trend. The Nd3+- and Yb3+-doped NCS glass-ceramics contain about 84.35±5 vol% of Na6Ca3Si6O18and 87.03±5 vol% of Na4Ca4Si6O18, respectively. The two crystal phases have the same basic structural units composed of 6-membered rings formed by 6 [SiO4] groups but the phase in the Yb3+-doped NCS glass-ceramics has a composition ratio more similar to its parent glass. The transmittance of the Yb3+-doped NCS glass-ceramics is higher than that of Nd3+-doped sample. Strong fluorescence emissions have been observed for the Nd3+-and Yb3+-doped NCS glass-ceramics, which indicates the potential of rare earth ions-doped highly crystalline transparent glass-ceramics for use as laser medium materials.
