We report the construction of a cost effective and low power consumption spin coater from a direct current (DC) brushless motor. The DC mechanical component is widely available in the central processing unit (CPU) cooler. This set up permits simple operation where the D voltage can be controlled manually in order to adjust the spin speed ranging from 1500 to 4500 resolution per minute (rpm). The spin speed stability can be determined by a tachometer against the spinning time. In order to evaluate the performance of the Amylose-75% Amylopectin thin films were successfully deposited on SiO thicknesses of the films were in the range of 96.1 nm to 225 nm.

Effect of Bi³⁺ Ion Concentration on Physicochemical, Optical and Catalytic Properties of One‐Pot Combustion Synthesized Nanocrystalline Bi‐Doped La₂O₃

La 2-2x Bi 2x O 3 (x = 0-0.04) nanocrystalline powders are synthesized by one-pot single step solution combustion method. 4 atom% Bi doped La 2 O 3 reveals the presence of both Bi 3 + and metallic Bi. Temperature programmed reduction (TPR) of La 2 O 3 and La 2 À 2x Bi 2x O 3 (x = 0.005-0.04) indicates that the oxygen storage capacity changes with the dopant (Bi) concentration. La 2-2x Bi 2x O 3 (x = 0.04) has less hygroscopic behavior compared to La 2 O 3 and shown enhanced stability in an open atmosphere. The direct band gap of La 2 O 3 and La(OH) 3 decreases significantly after Bi doping. Further, PL studies of Bi doped compounds show a blue emission at 458 nm due to 3 P 1-1 S 0 transition of the Bi 3 + ion substituted in La 2 O 3. Emission intensity is maximum with 0.5 atom percent Bi doping, which decreases gradually with increasing Bi 3 + ion concentration. Bi doping also modifies the catalytic activity of La 2 O 3, resulting in higher CO oxidation activity than unsubstituted La 2 O 3 .
