Lead halide perovskites are currently receiving increasing attention due to their potential to
combine easy active layers fabrication, tunable electronic and optical properties with …

Toward a higher degree of secure communication, great efforts have been made to develop
encryption and anticounterfeiting strategies. In particular, optical encryption with high …

Programmable random lasing pulses are highly desired due to their promising applications
in information security, flexible encoding systems, and smart imaging. However, the fixed …

We describe herein a flexible and tunable random laser made from a flexible poly
(dimethylsiloxane) substrate. The substrate is prepared by casting via soft lithography from a …

Three-dimensional organic–inorganic hybrid halide perovskites have been demonstrated as
great materials for applications in optoelectronics and photonics. However, their inherent …

Hybrid thin films that combine organic conjugated molecules and semiconductors
nanocrystals (NCs) have been deeply investigated in the previous years, due to their …

This paper reports the first experimental evidence of multiple band Amplified Spontaneous
Emission (ASE) in the blue spectral range from a thin film of poly (9, 9-dioctylfluorene)(PFO) …

Amplified Spontaneous Emission (ASE) threshold represents a crucial parameter often used
to establish if a material is a good candidate for applications to lasers. Even if the ASE …

In this paper we quantitatively investigate the effect of blending in an active polymer host on
the Amplified Spontaneous Emission (ASE) properties of poly [2-methoxy-5-(2 …
