In this work, for the first time, the property of particles to form close-packed layer in front of the freezing interface was used to increase the luminescent efficiency response for ruby and titanium-sapphire microcrystals water suspensions. An increase in the efficiency of luminescence response due to an increase in the concentration of particles at the freezing front, can be used for phase transition sensing. In addition, particles packing by freezing method can be used for tuning random laser generation or increasing the efficiency of different nonlinear optical effects in suspensions of particles.

冷冻激光微晶悬浮液——提高发光效率响应的新途径

在这项工作中，首次利用颗粒在冷冻界面前形成密堆积层的特性来提高红宝石和钛蓝宝石微晶水悬浮液的发光效率响应。由于冷冻前沿颗粒浓度的增加而导致发光响应效率的增加，可用于相变传感。此外，通过冷冻方法进行颗粒堆积可用于调节随机激光生成或提高颗粒悬浮液中不同非线性光学效应的效率。
