Abstract
In present work the influence of high excitation power density of laser diode on emission properties of Y2Si2O7:Nd3+ nanocrystals is reported. It was found that if a characteristic power threshold is exceeded intense broadband was observed in visible and infrared regions. It increased with a simultaneous decrease of f-f transitions. In particular, the influence of excitation power density and concentration of Nd3+ ions were investigated. The intensity of white emission was characterized by exponential dependence on excitation power density and threshold behavior. Moreover, it increased with the concentration of Nd3+ ions demonstrating exponential dependence due to the cooperative interaction between Nd3+ ions. The photocurrent accompanying the laser induced broadband white emission was measured. It increased exponentially with excitation power and Nd3+ concentration.
