Properties of ZnO nanocrystals prepared by radiation method

Non-thermal plasma-driven synthesis of Eu3+:Y2O3 nanosized phosphors

“…Another drawback of this method is violence of reaction, which really influence and limit mass production application. Despite the above-mentioned methods (Hreniak et al 2004 ; Lee and Choi 2005 ; Pechini 1967 ; Xu et al 2005 ; Song et al 2003 ) and the others presented elsewhere (Barta et al 2010 ; Chen et al 2005 ; Cuba et al 2010a , b , 2011 , 2012 ; Gbur et al 2011 ; Jang et al 2006 ; Tang et al 2003 ; Vollath and Szabo 2006 ; Zhang et al 2004 ) synthesis of nanocrystals using only water solutions of nitrates exposited for non-thermal plasma (NTP) is possible. The other method of synthesis of nanoparticles uses a plasma microwave reactor (Vollath and Szabo 2006 ), where the reaction of ionized gases takes place.…”

Advanced photochemical processes for the manufacture of nanopowders: an evaluation of long-term pilot plant operation

“…One of the promising preparation techniques relies on chemical reactions initiated and maintained by the absorption of ionizing or non-ionizing radiation; radiation-induced preparation methods utilizing high-energy ionizing radiation have proven their capability for synthesis of a broad range of nanocrystalline materials, as was reported for various oxides elsewhere. [6][7][8][9][10][11][12][13][14] They have several advantages, such as independence of the experimental conditions, low activation energy, high yields and high reaction rates. However, operating a source of ionizing radiation is required, which also increases requirements for qualified personnel and the cost of the process, including substantial capital costs.…”
