TLDR
The effective population inversion of 2 H11/2 from 4 S3/2 state of Er3+ ions can be achieved through the annihilation of phonons and random lasing action from BLF films embedded with Yb3+ /Er3+ codoped BLF nanocrystals is demonstrated.Abstract:
The effective population inversion of 2 H11/2 from 4 S3/2 state of Er3+ ions can be achieved through the annihilation of phonons; random lasing action from BLF films embedded with Yb3+ /Er3+ codoped BLF nanocrystals is demonstrated and high ambient temperature (>433 K) operation lasers with a very low excitation threshold (<530 nJ cm-2 ) are realized.read more
