Paper Abstract

In this work we report a detailed spectroscopic study of the near-infrared to visible upconversion luminescence in Erdoped lanthanum oxysulfide crystal powders after excitation of level 4I9/2. The analysis of the decay curves of the upconversion emission indicates that energy transfer upconversion is the main mechanism responsible for the green (4S3/2) and red (4F9/2) upconversion luminescence. The temperature dependence of the green upconverted emission from the two thermally coupled 2H11/2 and 4S3/2 levels has been analyzed in the 230 K- 300 K temperature range in order to check its availability as a temperature sensor.
