Photoluminescence in laser ablated nanostructured indium oxide thin films

Fabrication and photocatalytic property of α-Bi2O3 nanoparticles by femtosecond laser ablation in liquid

“…Hence preparation of nanostructured Bi 2 O 3 photocatalysts doubtless deserves to be taken into account in future research. In recent years, laser ablation of a solid target in a liquid environment has been widely used in the synthesis of nanocrystals and fabrication of nanostructures due to the following advantages: (i) a chemically "simple and clean" synthesis [10][11][12], (ii) an ambient conditions not extreme temperature and pressure [13][14][15], (iii) the new phase formation of nanocrystals may involve in both liquid and solid [10], and (iv) structure, size, and shape of the synthesized nanocrystals can be controlled by tuning laser parameters and applied assistances [16][17][18][19][20][21][22][23]. Furthermore, compared with other normal laser ablation, femtosecond laser ablation has some advantages, such as higher temperature and higher pressure in a local volume can be achieved, higher temperature phase materials can be fabricated, and smaller nanocrystals with narrow size distribution can be obtained [10,12].…”

Radiation Induced Synthesis of In2O3Nanoparticles - Part II: Synthesis of In2O3 Nanoparticles by Thermal Decomposition of Un-irradiated and γ-irradiated Indium Acetylacetonate

“…It is well known from literature that bulk In 2 O 3 cannot emit light at room temperature. However, PL emissions of the nanocrystalline In 2 O 3 samples are possible due to the effect of oxygen vacancies 20 and recently to indium inertial and their associated complex defects 21 . Figure 6 shows the RT-PL spectra of the as-synthesized In 2 O 3 nanoparticles.…”

Synthesis of In2o3 Nanowires for the Application of LPG Sensor

“…Because of these properties it has its application in sensors and detectors [3][4][5][6]. There are different techniques for fabricating one dimensional In2O3 nanostructure, they are thermal evaporation [7][8], pulse laser ablation [9], chemical vapour deposition [10], sputtering [11], vapour liquid solid condensation [12], atomic vapour deposition [13]. The main disadvantage with the above mentioned techniques is that the nanostructures obtained are not perpendicularly grown on the substrate.…”
