Red ceramic pigments of terbium-doped ceria prepared through classical and non-conventional coprecipitation routes

Effective synthesis route for red-brown pigments based on Ce – Pr – Fe – O and their potential application for near infrared reflective surface coating

“…have been reported with a red hue. [27][28][29][30][31] Disadvantages of such methods could be those relating to cost, need for high calcination temperatures, release of toxic gases, etc.…”

Optical and structural properties of nanostructured CeO2:Tb3+ film

“…In recent years some attempt have been performed for the preparation of RE ion doped cerium oxide by various techniques such as pyrolysis [4], solvothermal synthesis [2,14], sonochemical synthesis [15], the two-stage co-precipitation process [16,17], sol-gel process [1,8], solid-state ceramic reactions [18], microwave irradiation [19] and so on [14][15][16][17][18][19][20][21][22]. Relatively few reports are based on structural and optical properties of RE ions doped CeO 2 [1,[15][16][17][18][19].…”

“…Relatively few reports are based on structural and optical properties of RE ions doped CeO 2 [1,[15][16][17][18][19]. Fujihara et al, used spin-on/pyrolysis method for deposition of luminescent thin films of Eu 3+ and Sm 3+ doped CeO 2 on quartz glass substrate [4].…”

Temperature resistant red and purple ceramic pigments based on the solid solution series BaZn2−xNixSi2O7 and BaMg2−xNixSi2O7

“…In the case of chromium compounds there are problems concerning the toxicity provoked by the possibility of the formation of Cr 6þ [7]. Other pigments often do not exhibit the desired pure and bright colours [6].…”
