Yang In th is study sol-gel method is u sed to produce (Yb O ) ternary zinc aluminum phosphate glasses (P O -Al O - 2 3 2 5 2 3 (P O -Al O -Zn O) ZnO) doped with varying amount of rare earth oxide 2 5 2 3 (Yb O ). The physical properties, thermal properties, 2 3 optical properties, and structure of these glasses were ZnOZn (N O3)2 determined and studied. Results showed that for ZnO (Td)570 and Zn (NO3)2 series glasses: softening temperature (Td) (Tg)500 ( ) was at 570, transition temperature (Tg) was below 500 3.65~8.64 10-6/ ( 100-300) , thermal expansion coefficient () was 8.64 ~ 3.65 (H2O 901days, wt% loss) 10-6/ (100-300), and dissolution rate of water 5.2 10-8 g/cm2 min (H2O 90 1days, wt% loss) was 5.2 10-8g/cm2 *min . (Yb O ) The refractive index and glass density increased with an 2 3 increase of rare earth oxides ( Yb O ). 2 3 Th is stu dy u sed Fou r ier in fr ar ed sp ectr o
