Abstract

Intense visible to uv up-conversion emission is observed in Er³⁺ doped crystals of CsMgCl₃, CsMgBr₃ and CsCdBr₃ when the ⁴S_3/2 (E), ²H_11/2 (F) and ⁴F_7/2 (G) states of Er³⁺ are pumped. The host crystals are of CsNiCl₃ type which exhibit a linear chain structure. These hosts incorporate trivalent rare earth ions such as Er³⁺ to form a M³⁺-vacancy-M³⁺ pair center. When both ions in an Er³⁺-vacancy-Er³⁺ center are simultaneously excited an efficient energy transfer occurs between Er³⁺ ions.
