Research ArticleOpen accessX-RAYS LUMINESCENCE, OPTICAL AND PHYSICAL STUDIES OF BI2O3-B2O3-SM2O3 GLASSES SYSTEMS. Rakpanich, J. Kaewkhao, N. Srisittipokakun et al.Sm3+-doped bismuth borate glasses of the composition (50-x) SiO2: 50B2O3: xSm2O3 (where x = 0.00, 0.50, 1.00, 1.50, 2.00 and 2.50 mol%) have been synthesized by conventional melt quenching technique. In order to understand the role of Sm2O3 in bismuth borate glasses, the density, molar volume, refractive index and optical absorption were investigated. The results show that density, molar volume … …Physics International, Vol. 4, Issue 1 · 18 Jul 2013 · 7,464 accessesView PDF Cite

Research ArticleOpen accessTHE STRUCTURE AND MECHANICAL PROPERTIES OF ALUMINA FILM PREPARED BY RF DIODE SPUTTERINGH. Panitchakan, P. LimsuwanAlumina (Al2O3) films were prepared on Al2O3-TiC substrates by RF diode sputtering. The target sputtering power was varied from 4 to 8 kW. The effects of target sputtering power on the structure and mechanical properties of alumina films were investigated. The results show that the structure of the alumina films deposited at all the target sputtering powers is amorphous. However, … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 6,897 accessesView PDF Cite

Research ArticleOpen accessOptical Investigation and Electronic Polarizability of Nd3+ Doped Soda-Lime-Silicate GlassesP. Chimalawong, J. Kaewkhao, P. LimsuwanProblem statement: This study researched on different physical and optical properties of Nd3+ doped soda-lime-silicate glass. The glasses containing Nd3+ in (65-x)SiO2: 25Na2O: 10CaO: xNd2O3 (where x = 0.0-5.0 mol%) had been prepared by melt-quenching method. The density and molar volume increase with increasing of Nd2O3 concentration due to increasing of Non Bridging Oxygen (NBOs) in glass matrix. The optical … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,149 accessesView PDF Cite
