ZHIWEI LUO1, ANXIAN LU1,*
High UV transmitting Glasses with c omposition 10 SrO 10 ZnO 33.3P 2 O 5 xB 2 O 3 --(46.7 x)SiO 2 have been prepared using the normal melt quench technique. Glass transition temperatures ( T g ) and thermal expansion coefficients CTE ) were determined using thermo mechanical analysis The optical studies in the UV-visible region for these glasses show different cut-off and transmitting window depending on composition composition. Increasing the B2O3 content to 16.67 mole% in the glasses can enhance the UV transmittance to greater than 60% at 200 nm. The values of both of the optical band gap (Eopt) and Urbach energy (ΔE) were calculated from optical absorption data. Generally, a novel high UV-transmitting glass was obtained successfully, and it is possible to produce glasses of high UV-transmittance using common commercial reagents at a relatively lowlower cost..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
