Very few devices are capable to measure temperature with high precision and sensitive, mainly in the micro and nanoscale. It is known that for biological applications it is required high sensitivity devices in a short temperature range (288–323 K).

High red photoluminescence emission has been obtained at room temperature in Eu3+-doped yttrium oxide thin films following thermal treatment. Films with different thicknesses were deposited on Si(1 0 0) and Si(1 1 1) substrates via electron beam evap

Processes involving visible to infrared energy conversion are presented for Pr3+–Yb3+ co-doped fluoroindate glasses. The emission in the visible and infrared regions, the luminescence decay time of the Pr3+:3P0 → 3H4 (482 nm), Pr3+:1D2 → 3H6 (8
