Crystal Structures and Properties

The glass formation region, crystalline phases, second harmonic (SH) generation, and Nd:yttrium aluminum garnet (YAG) laser‐induced crystallization in the Sm 2 O 3 –Bi 2 O 3 –B 2 O 3 system were clarified. The crystalline phases of Bi 4 B 2 O 9 , Bi 3 B 5 O 12 , BiBO 3 , Sm x Bi 1− x BO 3 , and SmB 3 O 6 were formed through the usual crystallization in an electric furnace. The crystallized glasses consisting of BiBO 3 and Sm x Bi 1− x BO 3 showed SH generations. The formation of the nonlinear optical BiB 3 O 6 phase was not confirmed. The formation (writing) region of crystal lines consisting of Sm x Bi 1− x BO 3 by YAG laser irradiation was determined, in which Sm 2 O 3 contents were∼10 mol%. The present study demonstrates that Sm 2 O 3 –Bi 2 O 3 –B 2 O 3 glasses are promising materials for optical functional applications.
