Narrow Visible Emission And Narrowing Band Gap In Ho3+ -Co Doped Y2O3: Eu3+ Nanopowders Prepared Via Sol- Combustion Route.

Abdub, G. Ali; Dejene, Francis B; Swart, Hendrik C. (IOSR Journal of Applied Physics, 2017-12)

Nanocrystalline Eu3+, Ho3+co-doped Y2O3 powders with a maximum size of 9.8 nm were prepared by the sol-combustion process, using Y (NO3).6HO2 as an oxidizer, europium and holonium nitrates as activators, thiourea as a fuel ...
