We use a new time-resolved temperature measurement technique to measure the temperature from gold nanorods on a surface with a thin AlGaN:Er layer immersed in air, water and ionic solutions. This technique relies on temperature-jump luminescence thermometry using time-resolved peak intensity changes from Erbium ions embedded in the AlGaN layer. Temperature is calculated by measuring the relative peak areas of the 2H11/2 ® 4I15/2 and 4S3/2 ® 4I15/2 bands from Er3+ ions using Boltzmann statistics. Finally, we compare our temperature-jump results to simulated thermal transfer data generated using finite element methods.
