The up-conversion optical emission temperature sensing of Er[Formula: see text]-doped (Ba[Formula: see text]Ca[Formula: see text])(Sn[Formula: see text]Ti[Formula: see text])O3 piezoelectric ceramic prepared via a conventional solid-state reaction method has been investigated in a range of 83–503[Formula: see text]K. There is a good linear relationship between the logarithm of the fluorescence intensity ratio of the green up-conversion emissions at 525[Formula: see text]nm and 550[Formula: see text]nm peaks (Ln([Formula: see text]/[Formula: see text])) and the inverse of temperature (1/[Formula: see text]). The maximum temperature sensitivity was found to be approximately 0.0051[Formula: see text]k[Formula: see text], suggesting that Er[Formula: see text]-doped (Ba[Formula: see text]Ca[Formula: see text])(Sn[Formula: see text]Ti[Formula: see text])O3 ceramic possesses potential application in optical non-contact temperature sensing.

Silicate Phosphors

Zinc silicate-based (Zn2SiO4:Eu3+) long afterglow phosphors were produced by solid state reaction method. The effects of borax and Eu2O3 additive on the properties of fabricated products have been studied. The results show that, there is not much difference in phase compositions within the borax additive amount; however, their SEM morphologies are different. Borax additive can increase the grain size of the product. Some sintering phenomena could be observed in the sample with Eu2O3 addition. The fluorescence spectroscopy results indicate that, the emission peak of the sample with Eu3+ additive located at 612nm, which may be a good candidate for red phosphor applications. The luminescent mechanism of Zn2SiO4:Eu3+ is also discussed.
