摘要：
In this work, we report the upconversion emission from Pr3+ and Nd3+ ions in potassium lead chloride crystal KPb2Cl5 after excitation in the F-4(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.
