Formation of a new hybrid complex via coordination interaction between 5,10,15-tritolyl-20-(4- and 3-pyridyl)porphyrin or 5,10,15-triphenyl-20-(4-pyridyl)porphyrin and the α-[MSiW11O39]6− Keggin-type polyoxometalate (M=Co2+ and Ni2+)

Evidence for the formation of a new complex based on the association of 5,10,15-tritolyl-20-(4- and 3-pyridyl)porphyrin or 5,10,15-triphenyl-20-(4-pyridyl)porphyrin and ?-[MSiW11O39]6?

Excited state absorption and energy-transfer mechanisms of up-conversion luminescence in Er3+-doped oxyfluoride glass ceramics at different temperatures

Oxyfluoride silicate glass SiO2?Al2O3?Na2CO3?NaF?LaF3?ErF3 was synthesized. The glass transition and crystallization temperatures were determined by differential thermal analysis.

Role of Ti4+ in the luminescence process of Al2O3:Si,Ti

l2O3:Si,Ti, prepared under oxidizing condition at high temperature, gives PL emission around 430nm when excited with 240nm. The Al2O3:C, TL/OSL phosphor, also shows emission around 430nm, which corresponds to characteristic emission of F-center.
