New near IR to near UV upconversion (UC) materials are required for the development of solid state lasers pumped by laser diodes. Two materials are reported: an air‐stable and efficient UC material emitting mostly in the yellowish‐green and a very promising UC compound, Ba 2 ErCl 7 , which is being further characterized spectroscopically. THe general requirements for UC materials are briefly discussed, and the preparation of Ba 2 ErCl 7 detailed. The intensity of individual emission bands is compared for known and new UC materials.
