Abstract

In this work, we report the upconversion emission from Pr³⁺ and Nd³⁺ ions in potassium lead chloride crystal KPb₂Cl₅after excitation in the ⁴F_5/2,3/2 levels of Nd³⁺ ions. We have observed violet, blue, green, orange, and red emissions at room temperature. Blue emission from Pr³⁺ ions is induced by near infrared laser excitation of Nd³⁺ through energy transfer from Nd³⁺ to Pr³⁺ ions. The mechanisms leading to the visible emissions have been investigated by studying the dependence of the upconversion luminescence on the excitation wavelength and intensity of the IR pump light.
