Zusammenfassung:This work presents an extensive study of the optical (linear/non-linear), mechanical properties and gamma-photon-shielding effectiveness of potassium titanate biso-phosphate with chemical form 50P 2 O 5 -30TiO 2 -(20-x)K 2 O-xBi 2 O 3 : x = 0 (Bi-0) mol%, 5 (Bi-5) mol%, 10 (Bi-10) mol%, 15 (Bi-15) mol%, and 20 (Bi-20) mol%.The linear refractive index (n optical ) increased from 2.41 for Bi-0 sample to 2.52 for Bi-20 sample. Both optical susceptibility (χ (3) ) and non-linear refractive index ( n 2 optical ) were enhanced with the addition of Bi 3+ ions in the investigated glasses. Bond compression bulk elastic ( K B-C ) modulus was found to decrease from 72.737 GPa for Bi-0 to 69.266 GPa for Bi-20 glasses, while Poisson’s ratio ( σ B-C ) for Bi-glasses was increased from 0.251 to 0.256. According to Makishima-Mackenzie (M-M) model, values of ( K M-M ) were decreased from 39.370 GPa to 36.775 GPa. In terms of mass and linear attenuation coefficients (MAC and LAC), the glasses take the order that (Bi-0) MAC,LAC
